File Search Stores

The File Search API provides a hosted question answering service for building Retrieval Augmented Generation (RAG) systems using Google's infrastructure.

Method: media.uploadToFileSearchStore

Uploads data to a FileSearchStore, preprocesses and chunks before storing it in a FileSearchStore Document.

Endpoint

  • Upload URI, for media upload requests:
 post https://generativelanguage.googleapis.com/upload/v1beta/{fileSearchStoreName=fileSearchStores/*}:uploadToFileSearchStore
  • Metadata URI, for metadata-only requests:
 post https://generativelanguage.googleapis.com/v1beta/{fileSearchStoreName=fileSearchStores/*}:uploadToFileSearchStore

Path parameters

fileSearchStoreName string

Required. Immutable. The name of the FileSearchStore to upload the file into. Example: fileSearchStores/my-file-search-store-123 It takes the form fileSearchStores/{filesearchstore}.

Request body

The request body contains data with the following structure:

Fields
displayName string

Optional. Display name of the created document.

customMetadata[] object (CustomMetadata)

Custom metadata to be associated with the data.

chunkingConfig object (ChunkingConfig)

Optional. Config for telling the service how to chunk the data. If not provided, the service will use default parameters.

mimeType string

Optional. MIME type of the data. If not provided, it will be inferred from the uploaded content.

Response body

If successful, the response body contains data with the following structure:

Fields
name string

The server-assigned name, which is only unique within the same service that originally returns it. If you use the default HTTP mapping, the name should be a resource name ending with operations/{unique_id}.

metadata object

Service-specific metadata associated with the operation. It typically contains progress information and common metadata such as create time. Some services might not provide such metadata. Any method that returns a long-running operation should document the metadata type, if any.

An object containing fields of an arbitrary type. An additional field "@type" contains a URI identifying the type. Example: { "id": 1234, "@type": "types.example.com/standard/id" }.

done boolean

If the value is false, it means the operation is still in progress. If true, the operation is completed, and either error or response is available.

result Union type
The operation result, which can be either an error or a valid response. If done == false, neither error nor response is set. If done == true, exactly one of error or response can be set. Some services might not provide the result. result can be only one of the following:
error object (Status)

The error result of the operation in case of failure or cancellation.

response object

The normal, successful response of the operation. If the original method returns no data on success, such as Delete, the response is google.protobuf.Empty. If the original method is standard Get/Create/Update, the response should be the resource. For other methods, the response should have the type XxxResponse, where Xxx is the original method name. For example, if the original method name is TakeSnapshot(), the inferred response type is TakeSnapshotResponse.

An object containing fields of an arbitrary type. An additional field "@type" contains a URI identifying the type. Example: { "id": 1234, "@type": "types.example.com/standard/id" }.
