This page shows you how to configure the fields to set up an app for structured data or for unstructured data with metadata.
Field settings help determine how Vertex AI Search uses fields in its results. You can use the Schema tab in the Google Cloud console to configure field settings for structured data and unstructured data with metadata.
Configuring field settings is available only for apps with data stores that have either structured data or unstructured data with metadata.
The following field settings are available:
| Field setting | Definition | Use case |
|---|---|---|
| Indexable | If a field is set to Indexable, Vertex AI Search can filter, order, and facet using this field. Setting boolean and object fields to indexable is not supported. | Search |
| Searchable | If a field is set to Searchable, recall for that
field in Vertex AI Search queries is improved. Only fields with
text values can be set to Searchable. |
Search |
| Dynamic facetable | If a field is set to Dynamic Facetable, Vertex AI Search can use that field as a dynamic facet. Dynamic facets can be automatically added to a search based on previous user behavior such as facet clicks and views. This setting is applicable only to fields that are indexable. | Search |
| Retreivable | If a field is set to Retrievable, Vertex AI Search returns the field in search results. | Search |
| Completable | If a field is set to Completable, Vertex AI Search uses the field's contents as search query suggestions. For more information, see Configure autocomplete. | Search |
| Filterable | If a field is set to Filterable, Vertex AI Search recommendations can use that field to filter recommendations results. For information about filtering recommendations, see Filter recommendations. | Recommendations |
Limitations
Field settings have the following limitations:
- You can configure up to 50 fields as indexable, searchable, or dynamic facetable.
- You can configure up to 30 fields as retrievable.
- To configure a field as dynamic facetable, it must first be configured as indexable.
- Changing the indexable setting requires re-indexing the data, which can take hours, especially for large data stores.
If you are configuring fields for a media search app and want detailed information about the fields in the schema, see About media documents and data stores.
