// Package developerknowledge provides access to the Developer Knowledge API.
//
// For product documentation, see: https://developers.google.com/knowledge
//
// # Library status
//
// These client libraries are officially supported by Google. However, this
// library is considered complete and is in maintenance mode. This means
// that we will address critical bugs and security issues but will not add
// any new features.
//
// When possible, we recommend using our newer
// [Cloud Client Libraries for Go](https://pkg.go.dev/cloud.google.com/go)
// that are still actively being worked and iterated on.
//
// # Creating a client
//
// Usage example:
//
//	import "google.golang.org/api/developerknowledge/v1alpha"
//	...
//	ctx := context.Background()
//	developerknowledgeService, err := developerknowledge.NewService(ctx)
//
// In this example, Google Application Default Credentials are used for
// authentication. For information on how to create and obtain Application
// Default Credentials, see https://developers.google.com/identity/protocols/application-default-credentials.
//
// # Other authentication options
//
// To use an API key for authentication (note: some APIs do not support API
// keys), use [google.golang.org/api/option.WithAPIKey]:
//
//	developerknowledgeService, err := developerknowledge.NewService(ctx, option.WithAPIKey("AIza..."))
//
// To use an OAuth token (e.g., a user token obtained via a three-legged OAuth
// flow, use [google.golang.org/api/option.WithTokenSource]:
//
//	config := &oauth2.Config{...}
//	// ...
//	token, err := config.Exchange(ctx, ...)
//	developerknowledgeService, err := developerknowledge.NewService(ctx, option.WithTokenSource(config.TokenSource(ctx, token)))
//
// See [google.golang.org/api/option.ClientOption] for details on options.

// Filter sets the optional parameter "filter": Applies a strict filter to the
// search results. The expression supports a subset of the syntax described at
// https://google.aip.dev/160. While `SearchDocumentChunks` returns
// DocumentChunks, the filter is applied to `DocumentChunk.document` fields.
// Supported fields for filtering: * `data_source` (STRING): The source of the
// document, e.g. `docs.cloud.google.com`. See
// https://developers.google.com/knowledge/reference/corpus-reference for the
// complete list of data sources in the corpus. * `update_time` (TIMESTAMP):
// The timestamp of when the document was last meaningfully updated. A
// meaningful update is one that changes document's markdown content or
// metadata. * `uri` (STRING): The document URI, e.g.
// `https://docs.cloud.google.com/bigquery/docs/tables`. STRING fields support
// `=` (equals) and `!=` (not equals) operators for **exact match** on the
// whole string. Partial match, prefix match, and regexp match are not
// supported. TIMESTAMP fields support `=`, `<`, `<=`, `>`, and `>=` operators.
// Timestamps must be in RFC-3339 format, e.g., "2025-01-01T00:00:00Z". You
// can combine expressions using `AND`, `OR`, and `NOT` (or `-`) logical
// operators. `OR` has higher precedence than `AND`. Use parentheses for
// explicit precedence grouping. Examples: * `data_source =
// "docs.cloud.google.com" OR data_source = "firebase.google.com" *
// `data_source != "firebase.google.com" * `update_time <
// "2024-01-01T00:00:00Z" * `update_time >= "2025-01-22T00:00:00Z" AND
// (data_source = "developer.chrome.com" OR data_source = "web.dev")` * `uri =
// "https://docs.cloud.google.com/release-notes" The `filter` string must not
// exceed 500 characters; values longer than 500 characters will result in an
