// 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.

	// in bytes. * `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`. INTEGER fields support
	// `=`, `<`, `<=`, `>`, and `>=` operators. 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: * Filter by `Document.content_length_bytes`:
	// `content_length_bytes < 50000` * `data_source = "docs.cloud.google.com" OR
	// data_source = "firebase.google.com" * `data_source !=

// 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". Note:
// Field names must be in `snake_case` (e.g., `data_source`). Values on the
// right-hand side of filtering expressions must be string literals enclosed in
// double quotes (e.g., "docs.cloud.google.com"). 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 =
