The `filter.scope` field controls which entity types are returned. At least one valid scope must be provided. Returns `200 OK` when all results fit in a single page. Returns `206 Partial Content` with a cursor in `meta.after` when additional pages are available. ### Request #### Body Data (required) Experimentation search payload. {% tab title="Model" %} | Parent field | Field | Type | Description | | --------------- | ---------------------------- | -------- | ------------------------------------------------------------------------------------------------------------------------- | | | data [*required*] | object | Data object for an experimentation search request. | | data | attributes [*required*] | object | Attributes for an experimentation search request. | | attributes | content_preview | object | Options to control content preview truncation. | | content_preview | limit | int64 | Maximum number of characters to include in content previews. | | attributes | filter [*required*] | object | Filter criteria for an experimentation search request. | | filter | include_deleted | boolean | When `true`, include soft-deleted entities alongside active ones. | | filter | is_deleted | boolean | When `true`, return only soft-deleted entities. | | filter | query | string | Free-text search query. | | filter | scope [*required*] | [string] | Entity types to search.
