That removes the need to operate a separate vector database and retrieval service for this feature—not the work of building a production application. You still need to manage source documents, authorization, ingestion state, failures, evaluation, and API costs.
What Gemini File Search manages—and what your Go service still owns
Google describes File Search as a Gemini API feature for retrieval-augmented generation (RAG). The managed part covers document import, chunking, embedding, indexing, and semantic retrieval. Your service calls the API to put content into a File Search store and later asks a Gemini model to answer with that store available as a tool. Google’s File Search documentation, last updated September 2, 2026 UTC, describes the feature and its current product limits.

“Zero infrastructure” is therefore a narrow architectural shorthand. It means you do not have to run a separate vector database and retrieval pipeline for this RAG feature. It does not mean there is no application infrastructure, operations work, or bill.

How to build the Go service
Implement the integration as a lifecycle, not as a single “upload and ask” request. Pin the SDK version in your Go module, verify the API and types against that version’s reference, and keep the chosen API environment consistent across client setup, credentials, and deployment configuration.
- Initialize the client for the intended API. Configure credentials through the supported method for that environment, and keep secrets out of source control and logs. The Go SDK supports more than one Google API environment, so use the matching service documentation rather than mixing assumptions.
- Create and register a File Search store. Treat the store identifier as application data: persist it with the tenant or corpus it belongs to, and resolve it server-side rather than accepting an unrestricted store identifier from a caller.
- Choose the embedding model deliberately. Google’s current File Search documentation describes
gemini-embedding-001for text embeddings andgemini-embedding-2for text and image search. Select based on the corpus and required modality, and confirm that the selected model and API support your intended workflow. - Import documents and track completion. Send source files to the selected store using the SDK’s documented File Search import flow. Record the source identity, target store, and operation status in your own system. Follow the returned ingestion operation until it completes or fails before treating the document as searchable.
- Generate answers with retrieval enabled. Configure File Search as a tool for the generation request and target the intended store. Ask the model to answer within the product’s requirements; do not assume retrieval will return a relevant result for every question.
- Handle citations when returned. Responses may contain file citation annotations. Parse and surface those references in the application when present, while allowing for responses without citations; the documentation does not promise a citation on every answer.
Exact method signatures and configuration fields can change with SDK versions. Use the pinned version’s reference instead of copying unversioned code: a sample that compiles against one release is not evidence that it compiles against another. The SDK repository and File Search API guide are the appropriate references for the version and API you deploy.

Keep ingestion and source lifecycle explicit
Maintain a source registry outside the File Search store. For each source, record enough information to identify its owner, origin, intended store, latest import state, and whether it should remain available. When a source changes, define whether your workflow replaces it, removes the old indexed content, or re-indexes it; do not treat a successful initial upload as a complete update policy. The temporary file upload and the indexed store data have different retention rules, so source replacement and deletion should be explicit lifecycle operations.
Recommended Free Tools
Put authorization before retrieval
Map authenticated users or tenants to permitted stores in your own service. Check authorization before making a generation request, and avoid letting user input choose an arbitrary store. If you attach metadata during import where supported, treat it as useful organization or filtering information—not as an authorization boundary unless the API’s current guarantees explicitly establish that role. Review the product’s data-handling terms for the deployment and data involved.
Make failures observable and recoverable
Track ingestion and query failures separately. Add input validation, bounded retries for transient API errors, request timeouts, and a way to resume or reconcile imports whose outcome is uncertain. Log operation identifiers, store references, status, latency, and usage data where available, but avoid logging sensitive document contents or user prompts unnecessarily. Evaluate answers and source attribution against representative questions before release and as the corpus changes.
Can File Search replace a vector database?
It can replace the separately operated retrieval layer for a workload that fits the documented File Search feature and its constraints. It is not a universal substitute for a custom RAG stack: the right choice depends on control, portability, corpus needs, modalities, governance, and measured cost and quality for your workload.

| Decision area | Managed File Search | Self-managed RAG stack |
|---|---|---|
| Operational burden | Google manages the documented import, indexing, and retrieval functions; your service still manages source and application lifecycle. | Your team operates and integrates the retrieval components it chooses. |
| Pipeline control | Convenient when the managed import, chunking, embedding, and retrieval behavior fits the use case. | Offers more direct control over parsing, chunking, embedding, reranking, and retrieval design. |
| Portability | Couples this retrieval path to Google’s API and supported models. | Can offer more flexibility to change providers or components, depending on implementation. |
| Scale and lifecycle | Subject to Google’s published per-document and store limits and store lifecycle behavior. | Bounded by the capacity, design, and operations of the system you build or operate. |
| Modality and integrations | Use only the modalities and request combinations currently supported by File Search. | Can be tailored to additional modalities or integrations, at the cost of building and maintaining them. |
| Cost and retrieval quality | Includes documented indexing and model-token charges; quality and total cost depend on the workload. | Costs depend on infrastructure and model choices; quality likewise requires workload-specific evaluation. |
The available product documentation does not establish that either approach has better retrieval quality or lower total cost for every corpus. Compare them using representative queries and the full expected ingestion and query workload, not just storage charges.

| Limit or constraint | Documented value or behavior | Practical implication |
|---|---|---|
| Maximum document size | 100 MB per document | Large sources may need to be split or handled through a different workflow. |
| Project store capacity | Free tier: 1 GB; Tier 1: 10 GB; Tier 2: 100 GB; Tier 3: 1 TB | Capacity depends on the project’s tier. Google recommends keeping each store below 20 GB for optimal retrieval latency; that is a product recommendation, not a latency guarantee. |
| Capacity accounting | Backend capacity includes source data and generated embeddings, typically about three times the input size | Do not estimate capacity from source-file size alone. |
| Live API | File Search is not supported in the Live API | A product requiring live audio interaction needs a different design or a separate supported request flow. |
| Other built-in grounding tools | Google says built-in grounding tools cannot be combined with one another in the same request; examples include File Search with Google Search grounding or URL Context. | If a request needs both retrieval from your store and another grounding tool, consider separate calls or another architecture, and verify current API behavior. |
| Audio and video | Audio and video formats are currently unsupported by File Search | Do not assume that uploading those formats makes their contents searchable. |
Temporary uploads are not the same as indexed data
Google documents that a temporary raw File object is deleted after 48 hours. Data imported into a File Search store persists until it is deleted; embeddings persist until manually deleted or the model is deprecated. These are distinct lifetimes, so the 48-hour retention of a temporary upload does not describe how long indexed store content remains. Include deletion and re-indexing in your application’s data lifecycle.
How much does Gemini File Search cost?
Google says File Search storage and query-time embeddings are free. That does not make a RAG application free: indexing embeddings are billed according to embedding pricing, retrieved-document context tokens are billed as regular input tokens, and the model’s usual input and output charges still apply. See Google’s API pricing for current rates.
| Cost component | Google’s documented treatment |
|---|---|
| File Search storage | Free |
| Query-time embeddings | Free |
| Indexing embeddings | Charged according to embedding pricing |
| Retrieved document context | Counted and billed as regular context tokens |
| Gemini generation | Normal model input and output pricing applies |
A monthly estimate needs workload assumptions: how much content is newly indexed or re-indexed, how many queries run, how much retrieved context is included, and which generation model and rates apply. Because the pricing page can change, use its current rates and your expected usage rather than treating “free storage” as a total-cost estimate.
What to validate before production
The product documentation establishes feature behavior and published limits, not the retrieval precision or recall, latency, availability, regulatory suitability, or production readiness of a particular deployment. Test and review those questions against your own corpus, users, and contractual requirements.
Quick Recap
- Retrieval and answer quality: Build a representative evaluation set, including questions with no supported answer, and inspect whether the retrieved source content is relevant.
- Tenant isolation: Test that each identity can reach only its authorized store and that import, deletion, and query paths enforce the same mapping.
- Failure handling: Exercise failed and incomplete imports, API errors, timeouts, retries, and source updates so the application does not present stale or unindexed content as current.
- Data governance: Review applicable Google product and contractual terms for the data, region, and regulatory obligations in scope; do not infer compliance suitability from the existence of a managed service.
- Cost under load: Measure indexing and query usage with the models and context sizes you expect to use, then project against current pricing.
- Integration fit: Confirm that the modality and grounding combinations your product needs are supported by the API version you deploy.
