experimental[This API is *experimental* and may be changed or removed completely in a future release. The underlying Upgrade Assistant concepts are stable, but the APIs for managing Upgrade Assistant are currently experimental.]
experimental[] In {es} 7.0 and later, some query types, such as Simple Query String, have a limit to the number of fields they can query against.
To configure the cap in {es}, set the `indices.query.bool.max_clause_count` cluster setting, which is 1024 by default.
Starting in Elasticsearch 7.0, some query types such as Simple Query String, have a limit to the number of fields they will query against. You can configure this cap in Elasticsearch by setting the `indices.query.bool.max_clause_count` cluster setting, which is 1024 by default.
For indices with more fields than this cap, you can add the `index.query.default_field` index setting to inform Elasticsearch which fields to use by default when no field is specified for a query. This API assists in adding this setting to an index in Elasticsearch.
For indices with more fields than the cap, add the `index.query.default_field` index setting to inform {es} which
fields to use by default when no field is specified for a query. Use the add default field API to add the `index.query.default_field` setting to an {es} index.
[[upgrade-assistant-api-default-field-request]]
==== Request
To add the `index.query.default_field` setting to an index, submit a POST request to the `/api/upgrade_assistant/add_query_default_field/<index>` endpoint:
Note: You cannot access this endpoint via the Console in Kibana.
To add the `index.query.default_field` setting to an {es} index, submit a POST request to `/api/upgrade_assistant/add_query_default_field/<index>`:

Kibana will add the `index.query.default_field` index setting to the specified index by generating an array of all fields from the index's mapping that are any of the types specified in `fieldTypes`. Optionally, any other fields specified in `otherFields` will be appended to the array of default fields.
To add the `index.query.default_field` index setting to the specified index, {kib} generates an array of all fields from the index mapping.
