# IsUserBased Criterion

IsUserBased Search Criterion

The [`IsUserBased` Search Criterion](https://doc.ibexa.co/en/latest/api/php_api/php_api_reference/classes/Ibexa-Contracts-Core-Repository-Values-Content-Query-Criterion-IsUserBased.html) searches for content that plays the role of a User account.

> **Note: Note**
>
> In the default setup only the user content type is treated as user accounts. However, you can also [set other content types to be treated as such](https://doc.ibexa.co/en/latest/administration/configuration/repository_configuration/#user-identifiers).

## Arguments

- (optional) `value` - bool representing whether to search for User-based (default `true`) or non-User-based content

## Limitations

The `IsUserBased` Criterion isn't available in Solr or Elasticsearch engines.
