google-gemini-file-search Build document Q&A and searchable knowledge bases with Google Gemini File Search - fully managed RAG with automatic chunking, embeddings, and citations. Upload 100+ file formats (PDF, Word, Excel, code), configure semantic search, and query with natural language. Use when: building document Q&A systems, creating searchable knowledge bases, implementing semantic search without managing embeddings, indexing large document collections (100+ formats), or troubleshooting document immutability errors (delete+re-upload required), storage quota issues (3x input size for embeddings), chunking configuration (500 tokens/chunk recommended), metadata limits (20 key-value pairs max), indexing cost surprises ($0.15/1M tokens one-time), operation polling timeouts (wait for done: true), force delete errors, or model compatibility (Gemini 2.5 Pro/Flash only).

Google Gemini File Search Setup

Overview

Google Gemini File Search is a fully managed RAG system. Upload documents (100+ formats: PDF, Word, Excel, code) and query with natural language—automatic chunking, embeddings, semantic search, and citations.

What This Skill Provides:

  • Complete @google/genai File Search API setup
  • 8 documented errors with prevention strategies
  • Chunking best practices for optimal retrieval
  • Cost optimization ($0.15/1M tokens indexing, 3x storage multiplier)
  • Cloudflare Workers + Next.js integration templates

Prerequisites

1. Google AI API Key

Create an API key at https://aistudio.google.com/apikey

Free Tier Limits:

  • 1 GB storage (total across all file search stores)
  • 1,500 requests per day
  • 1 million tokens per minute

Paid Tier Pricing:

  • Indexing: $0.15 per 1M input tokens (one-time)
  • Storage: Free (Tier 1: 10 GB, Tier 2: 100 GB, Tier 3: 1 TB)
  • Query-time embeddings: Free (retrieved context counts as input tokens)

2. Node.js Environment

Minimum Version: Node.js 18+ (v20+ recommended)

node --version  # Should be >=18.0.0

3. Install @google/genai SDK

npm install @google/genai
# or
pnpm add @google/genai
# or
yarn add @google/genai

Current Stable Version: 1.30.0+ (verify with npm view @google/genai version)

⚠️ Important: File Search API requires @google/genai v1.29.0 or later. Earlier versions do not support File Search. The API was added in v1.29.0 (November 5, 2025).

4. TypeScript Configuration (Optional but Recommended)

{
  "compilerOptions": {
    "target": "ES2020",
    "module": "ESNext",
    "moduleResolution": "node",
    "esModuleInterop": true,
    "strict": true,
    "skipLibCheck": true
  }
}

Common Errors Prevented

This skill prevents 8 common errors encountered when implementing File Search:

Error 1: Document Immutability

Symptom:

Error: Documents cannot be modified after indexing

Cause: Documents are immutable once indexed. There is no PATCH or UPDATE operation.

Prevention: Use the delete+re-upload pattern for updates:

// ❌ WRONG: Trying to update document (no such API)
await ai.fileSearchStores.documents.update({
  name: documentName,
  customMetadata: { version: '2.0' }
})

// ✅ CORRECT: Delete then re-upload
const docs = await ai.fileSearchStores.documents.list({
  parent: fileStore.name
})

const oldDoc = docs.documents.find(d => d.displayName === 'manual.pdf')
if (oldDoc) {
  await ai.fileSearchStores.documents.delete({
    name: oldDoc.name,
    force: true
  })
}

await ai.fileSearchStores.uploadToFileSearchStore({
  name: fileStore.name,
  file: fs.createReadStream('manual-v2.pdf'),
  config: { displayName: 'manual.pdf' }
})

Source: https://ai.google.dev/api/file-search/documents

Error 2: Storage Quota Exceeded

Symptom:

Error: Quota exceeded. Expected 1GB limit, but 3.2GB used.

Cause: Storage calculation includes input files + embeddings + metadata. Total storage ≈ 3x input size.

Prevention: Calculate storage before upload:

// ❌ WRONG: Assuming storage = file size
const fileSize = fs.statSync('data.pdf').size // 500 MB
// Expect 500 MB usage → WRONG

// ✅ CORRECT: Account for 3x multiplier
const fileSize = fs.statSync('data.pdf').size // 500 MB
const estimatedStorage = fileSize * 3 // 1.5 GB (embeddings + metadata)
console.log(`Estimated storage: ${estimatedStorage / 1e9} GB`)

// Check if within quota before upload
if (estimatedStorage > 1e9) {
  console.warn('⚠️ File may exceed free tier 1 GB limit')
}

Error 3: Incorrect Chunking Configuration

Symptom: Poor retrieval quality, irrelevant results, or context cutoff mid-sentence.

Cause: Default chunking may not be optimal for your content type.

Prevention: Use recommended chunking strategy:

// ❌ WRONG: Using defaults without testing
await ai.fileSearchStores.uploadToFileSearchStore({
  name: fileStore.name,
  file: fs.createReadStream('docs.pdf')
  // Default chunking may be too large or too small
})

// ✅ CORRECT: Configure chunking for precision
await ai.fileSearchStores.uploadToFileSearchStore({
  name: fileStore.name,
  file: fs.createReadStream('docs.pdf'),
  config: {
    chunkingConfig: {
      whiteSpaceConfig: {
        maxTokensPerChunk: 500,  // Smaller chunks = more precise retrieval
        maxOverlapTokens: 50     // 10% overlap prevents context loss
      }
    }
  }
})

Chunking Guidelines:

  • Technical docs/code: 500 tokens/chunk, 50 overlap
  • Prose/articles: 800 tokens/chunk, 80 overlap
  • Legal/contracts: 300 tokens/chunk, 30 overlap (high precision)

Source: https://www.philschmid.de/gemini-file-search-javascript

Error 4: Metadata Limits Exceeded

Symptom:

Error: Maximum 20 custom metadata key-value pairs allowed

Cause: Each document can have at most 20 metadata fields.

Prevention: Design compact metadata schema:

// ❌ WRONG: Too many metadata fields
await ai.fileSearchStores.uploadToFileSearchStore({
  name: fileStore.name,
  file: fs.createReadStream('doc.pdf'),
  config: {
    customMetadata: {
      doc_type: 'manual',
      version: '1.0',
      author: 'John Doe',
      department: 'Engineering',
      created_date: '2025-01-01',
      // ... 18 more fields → Error!
    }
  }
})

// ✅ CORRECT: Use hierarchical keys or JSON strings
await ai.fileSearchStores.uploadToFileSearchStore({
  name: fileStore.name,
  file: fs.createReadStream('doc.pdf'),
  config: {
    customMetadata: {
      doc_type: 'manual',
      version: '1.0',
      author_dept: 'John Doe|Engineering',  // Combine related fields
      dates: JSON.stringify({                // Or use JSON for complex data
        created: '2025-01-01',
        updated: '2025-01-15'
      })
    }
  }
})

Source: https://ai.google.dev/api/file-search/documents

Error 5: Indexing Cost Surprises

Symptom: Unexpected bill for $375 after uploading 10 GB of documents.

Cause: Indexing costs are one-time but calculated per input token ($0.15/1M tokens).

Prevention: Estimate costs before indexing:

// ❌ WRONG: No cost estimation
await uploadAllDocuments(fileStore.name, './data') // 10 GB uploaded → $375 surprise

// ✅ CORRECT: Calculate costs upfront
const totalSize = getTotalDirectorySize('./data') // 10 GB
const estimatedTokens = (totalSize / 4) // Rough estimate: 1 token ≈ 4 bytes
const indexingCost = (estimatedTokens / 1e6) * 0.15

console.log(`Estimated indexing cost: $${indexingCost.toFixed(2)}`)
console.log(`Estimated storage: ${(totalSize * 3) / 1e9} GB`)

// Confirm before proceeding
const proceed = await confirm(`Proceed with indexing? Cost: $${indexingCost.toFixed(2)}`)
if (proceed) {
  await uploadAllDocuments(fileStore.name, './data')
}

Cost Examples:

  • 1 GB text ≈ 250M tokens = $37.50 indexing
  • 100 MB PDF ≈ 25M tokens = $3.75 indexing
  • 10 MB code ≈ 2.5M tokens = $0.38 indexing

Source: https://ai.google.dev/pricing

Error 6: Not Polling Operation Status

Symptom: Query returns no results immediately after upload, or incomplete indexing.

Cause: File uploads are processed asynchronously. Must poll operation until done: true.

Prevention: Always poll operation status:

// ❌ WRONG: Assuming upload is instant
const operation = await ai.fileSearchStores.uploadToFileSearchStore({
  name: fileStore.name,
  file: fs.createReadStream('large.pdf')
})
// Immediately query → No results!

// ✅ CORRECT: Poll until indexing complete
const operation = await ai.fileSearchStores.uploadToFileSearchStore({
  name: fileStore.name,
  file: fs.createReadStream('large.pdf')
})

// Poll every 1 second
while (!operation.done) {
  await new Promise(resolve => setTimeout(resolve, 1000))
  operation = await ai.operations.get({ name: operation.name })
  console.log(`Indexing progress: ${operation.metadata?.progress || 'processing...'}`)
}

if (operation.error) {
  throw new Error(`Indexing failed: ${operation.error.message}`)
}

console.log('✅ Indexing complete:', operation.response.displayName)

Source: https://ai.google.dev/api/file-search/file-search-stores#uploadtofilesearchstore

Error 7: Forgetting Force Delete

Symptom:

Error: Cannot delete store with documents. Set force=true.

Cause: Stores with documents require force: true to delete (prevents accidental deletion).

Prevention: Always use force: true when deleting non-empty stores:

// ❌ WRONG: Trying to delete store with documents
await ai.fileSearchStores.delete({
  name: fileStore.name
})
// Error: Cannot delete store with documents

// ✅ CORRECT: Use force delete
await ai.fileSearchStores.delete({
  name: fileStore.name,
  force: true  // Deletes store AND all documents
})

// Alternative: Delete documents first
const docs = await ai.fileSearchStores.documents.list({ parent: fileStore.name })
for (const doc of docs.documents || []) {
  await ai.fileSearchStores.documents.delete({
    name: doc.name,
    force: true
  })
}
await ai.fileSearchStores.delete({ name: fileStore.name })

Source: https://ai.google.dev/api/file-search/file-search-stores#delete

Error 8: Using Unsupported Models

Symptom:

Error: File Search is only supported for Gemini 2.5 Pro and Flash models

Cause: File Search requires Gemini 2.5 Pro or Gemini 2.5 Flash. Gemini 1.5 models are not supported.

Prevention: Always use 2.5 models:

// ❌ WRONG: Using Gemini 1.5 model
const response = await ai.models.generateContent({
  model: 'gemini-1.5-pro',  // Not supported!
  contents: 'What is the installation procedure?',
  config: {
    tools: [{
      fileSearch: { fileSearchStoreNames: [fileStore.name] }
    }]
  }
})

// ✅ CORRECT: Use Gemini 2.5 models
const response = await ai.models.generateContent({
  model: 'gemini-2.5-flash',  // ✅ Supported (fast, cost-effective)
  // OR
  // model: 'gemini-2.5-pro',   // ✅ Supported (higher quality)
  contents: 'What is the installation procedure?',
  config: {
    tools: [{
      fileSearch: { fileSearchStoreNames: [fileStore.name] }
    }]
  }
})

Source: https://ai.google.dev/gemini-api/docs/file-search

Setup Instructions

Step 1: Initialize Client

import { GoogleGenAI } from '@google/genai'
import fs from 'fs'

// Initialize client with API key
const ai = new GoogleGenAI({
  apiKey: process.env.GOOGLE_API_KEY
})

// Verify API key is set
if (!process.env.GOOGLE_API_KEY) {
  throw new Error('GOOGLE_API_KEY environment variable is required')
}

Step 2: Create File Search Store

// Create a store (container for documents)
const fileStore = await ai.fileSearchStores.create({
  config: {
    displayName: 'my-knowledge-base',  // Human-readable name
    // Optional: Add store-level metadata
    customMetadata: {
      project: 'customer-support',
      environment: 'production'
    }
  }
})

console.log('Created store:', fileStore.name)
// Output: fileSearchStores/abc123xyz...

Finding Existing Stores:

// List all stores (paginated)
const stores = await ai.fileSearchStores.list({
  pageSize: 20  // Max 20 per page
})

// Find by display name
let targetStore = null
let pageToken = null

do {
  const page = await ai.fileSearchStores.list({ pageToken })
  targetStore = page.fileSearchStores.find(
    s => s.displayName === 'my-knowledge-base'
  )
  pageToken = page.nextPageToken
} while (!targetStore && pageToken)

if (targetStore) {
  console.log('Found existing store:', targetStore.name)
} else {
  console.log('Store not found, creating new one...')
}

Step 3: Upload Documents

Single File Upload:

const operation = await ai.fileSearchStores.uploadToFileSearchStore({
  name: fileStore.name,
  file: fs.createReadStream('./docs/manual.pdf'),
  config: {
    displayName: 'Installation Manual',
    customMetadata: {
      doc_type: 'manual',
      version: '1.0',
      language: 'en'
    },
    chunkingConfig: {
      whiteSpaceConfig: {
        maxTokensPerChunk: 500,
        maxOverlapTokens: 50
      }
    }
  }
})

// Poll until indexing complete
while (!operation.done) {
  await new Promise(resolve => setTimeout(resolve, 1000))
  operation = await ai.operations.get({ name: operation.name })
}

console.log('✅ Indexed:', operation.response.displayName)

Batch Upload (Concurrent):

const filePaths = [
  './docs/manual.pdf',
  './docs/faq.md',
  './docs/troubleshooting.docx'
]

// Upload all files concurrently
const uploadPromises = filePaths.map(filePath =>
  ai.fileSearchStores.uploadToFileSearchStore({
    name: fileStore.name,
    file: fs.createReadStream(filePath),
    config: {
      displayName: filePath.split('/').pop(),
      customMetadata: {
        doc_type: 'support',
        source_path: filePath
      },
      chunkingConfig: {
        whiteSpaceConfig: {
          maxTokensPerChunk: 500,
          maxOverlapTokens: 50
        }
      }
    }
  })
)

const operations = await Promise.all(uploadPromises)

// Poll all operations
for (const operation of operations) {
  let op = operation
  while (!op.done) {
    await new Promise(resolve => setTimeout(resolve, 1000))
    op = await ai.operations.get({ name: op.name })
  }
  console.log('✅ Indexed:', op.response.displayName)
}

Step 4: Query with File Search

Basic Query:

const response = await ai.models.generateContent({
  model: 'gemini-2.5-flash',
  contents: 'What are the safety precautions for installation?',
  config: {
    tools: [{
      fileSearch: {
        fileSearchStoreNames: [fileStore.name]
      }
    }]
  }
})

console.log('Answer:', response.text)

// Access citations
const grounding = response.candidates[0].groundingMetadata
if (grounding?.groundingChunks) {
  console.log('\nSources:')
  grounding.groundingChunks.forEach((chunk, i) => {
    console.log(`${i + 1}. ${chunk.retrievedContext?.title || 'Unknown'}`)
    console.log(`   URI: ${chunk.retrievedContext?.uri || 'N/A'}`)
  })
}

Query with Metadata Filtering:

const response = await ai.models.generateContent({
  model: 'gemini-2.5-flash',
  contents: 'How do I reset the device?',
  config: {
    tools: [{
      fileSearch: {
        fileSearchStoreNames: [fileStore.name],
        // Filter to only search troubleshooting docs in English, version 1.0
        metadataFilter: 'doc_type="troubleshooting" AND language="en" AND version="1.0"'
      }
    }]
  }
})

console.log('Answer:', response.text)

Metadata Filter Syntax:

  • AND: key1="value1" AND key2="value2"
  • OR: key1="value1" OR key1="value2"
  • Parentheses: (key1="a" OR key1="b") AND key2="c"

Step 5: List and Manage Documents

// List all documents in store
const docs = await ai.fileSearchStores.documents.list({
  parent: fileStore.name,
  pageSize: 20
})

console.log(`Total documents: ${docs.documents?.length || 0}`)

docs.documents?.forEach(doc => {
  console.log(`- ${doc.displayName} (${doc.name})`)
  console.log(`  Metadata:`, doc.customMetadata)
})

// Get specific document details
const docDetails = await ai.fileSearchStores.documents.get({
  name: docs.documents[0].name
})

console.log('Document details:', docDetails)

// Delete document
await ai.fileSearchStores.documents.delete({
  name: docs.documents[0].name,
  force: true
})

Step 6: Cleanup

// Delete entire store (force deletes all documents)
await ai.fileSearchStores.delete({
  name: fileStore.name,
  force: true
})

console.log('✅ Store deleted')

Recommended Chunking Strategies

Chunking configuration significantly impacts retrieval quality. Adjust based on content type:

Technical Documentation

chunkingConfig: {
  whiteSpaceConfig: {
    maxTokensPerChunk: 500,   // Smaller chunks for precise code/API lookup
    maxOverlapTokens: 50      // 10% overlap
  }
}

Best for: API docs, SDK references, code examples, configuration guides

Prose and Articles

chunkingConfig: {
  whiteSpaceConfig: {
    maxTokensPerChunk: 800,   // Larger chunks preserve narrative flow
    maxOverlapTokens: 80      // 10% overlap
  }
}

Best for: Blog posts, news articles, product descriptions, marketing materials

Legal and Contracts

chunkingConfig: {
  whiteSpaceConfig: {
    maxTokensPerChunk: 300,   // Very small chunks for high precision
    maxOverlapTokens: 30      // 10% overlap
  }
}

Best for: Legal documents, contracts, regulations, compliance docs

FAQ and Support

chunkingConfig: {
  whiteSpaceConfig: {
    maxTokensPerChunk: 400,   // Medium chunks (1-2 Q&A pairs)
    maxOverlapTokens: 40      // 10% overlap
  }
}

Best for: FAQs, troubleshooting guides, how-to articles

General Rule: Maintain 10% overlap (overlap = chunk size / 10) to prevent context loss at chunk boundaries.

Metadata Best Practices

Design metadata schema for filtering and organization:

Example: Customer Support Knowledge Base

customMetadata: {
  doc_type: 'faq' | 'manual' | 'troubleshooting' | 'guide',
  product: 'widget-pro' | 'widget-lite',
  version: '1.0' | '2.0',
  language: 'en' | 'es' | 'fr',
  category: 'installation' | 'configuration' | 'maintenance',
  priority: 'critical' | 'normal' | 'low',
  last_updated: '2025-01-15',
  author: 'support-team'
}

Query Example:

metadataFilter: 'product="widget-pro" AND (doc_type="troubleshooting" OR doc_type="faq") AND language="en"'

Example: Legal Document Repository

customMetadata: {
  doc_type: 'contract' | 'regulation' | 'case-law' | 'policy',
  jurisdiction: 'US' | 'EU' | 'UK',
  practice_area: 'employment' | 'corporate' | 'ip' | 'tax',
  effective_date: '2025-01-01',
  status: 'active' | 'archived',
  confidentiality: 'public' | 'internal' | 'privileged'
}

Example: Code Documentation

customMetadata: {
  doc_type: 'api-reference' | 'tutorial' | 'example' | 'changelog',
  language: 'javascript' | 'python' | 'java' | 'go',
  framework: 'react' | 'nextjs' | 'express' | 'fastapi',
  version: '1.2.0',
  difficulty: 'beginner' | 'intermediate' | 'advanced'
}

Tips:

  • Use consistent key naming (snake_case or camelCase)
  • Limit to most important filterable fields (20 max)
  • Use enums/constants for values (easier filtering)
  • Include version and date fields for time-based filtering

Cost Optimization

1. Deduplicate Before Upload

// Track uploaded file hashes to avoid duplicates
const uploadedHashes = new Set<string>()

async function uploadWithDeduplication(filePath: string) {
  const fileHash = await getFileHash(filePath)

  if (uploadedHashes.has(fileHash)) {
    console.log(`Skipping duplicate: ${filePath}`)
    return
  }

  await ai.fileSearchStores.uploadToFileSearchStore({
    name: fileStore.name,
    file: fs.createReadStream(filePath)
  })

  uploadedHashes.add(fileHash)
}

2. Compress Large Files

// Convert images to text before indexing (OCR)
// Compress PDFs (remove images, use text-only)
// Use markdown instead of Word docs (smaller size)

3. Use Metadata Filtering to Reduce Query Scope

// ❌ EXPENSIVE: Search all 10GB of documents
const response = await ai.models.generateContent({
  model: 'gemini-2.5-flash',
  contents: 'Reset procedure?',
  config: {
    tools: [{ fileSearch: { fileSearchStoreNames: [fileStore.name] } }]
  }
})

// ✅ CHEAPER: Filter to only troubleshooting docs (subset)
const response = await ai.models.generateContent({
  model: 'gemini-2.5-flash',
  contents: 'Reset procedure?',
  config: {
    tools: [{
      fileSearch: {
        fileSearchStoreNames: [fileStore.name],
        metadataFilter: 'doc_type="troubleshooting"'  // Reduces search scope
      }
    }]
  }
})

4. Choose Flash Over Pro for Cost Savings

// Gemini 2.5 Flash is 10x cheaper than Pro for queries
// Use Flash unless you need Pro's advanced reasoning

// Development/testing: Use Flash
model: 'gemini-2.5-flash'

// Production (high-stakes answers): Use Pro
model: 'gemini-2.5-pro'

5. Monitor Storage Usage

// List stores and estimate storage
const stores = await ai.fileSearchStores.list()

for (const store of stores.fileSearchStores || []) {
  const docs = await ai.fileSearchStores.documents.list({
    parent: store.name
  })

  console.log(`Store: ${store.displayName}`)
  console.log(`Documents: ${docs.documents?.length || 0}`)
  // Estimate storage (3x input size)
  console.log(`Estimated storage: ~${(docs.documents?.length || 0) * 10} MB`)
}

Testing & Verification

Verify Store Creation

const store = await ai.fileSearchStores.get({
  name: fileStore.name
})

console.assert(store.displayName === 'my-knowledge-base', 'Store name mismatch')
console.log('✅ Store created successfully')

Verify Document Indexing

const docs = await ai.fileSearchStores.documents.list({
  parent: fileStore.name
})

console.assert(docs.documents?.length > 0, 'No documents indexed')
console.log(`✅ ${docs.documents?.length} documents indexed`)

Verify Query Functionality

const response = await ai.models.generateContent({
  model: 'gemini-2.5-flash',
  contents: 'What is this knowledge base about?',
  config: {
    tools: [{ fileSearch: { fileSearchStoreNames: [fileStore.name] } }]
  }
})

console.assert(response.text.length > 0, 'Empty response')
console.log('✅ Query successful:', response.text.substring(0, 100) + '...')

Verify Citations

const response = await ai.models.generateContent({
  model: 'gemini-2.5-flash',
  contents: 'Provide a specific answer with citations.',
  config: {
    tools: [{ fileSearch: { fileSearchStoreNames: [fileStore.name] } }]
  }
})

const grounding = response.candidates[0].groundingMetadata
console.assert(
  grounding?.groundingChunks?.length > 0,
  'No grounding/citations returned'
)
console.log(`✅ ${grounding?.groundingChunks?.length} citations returned`)
