# MatchNone Criterion

The [`MatchNone` Search Criterion](https://doc.ibexa.co/en/latest/api/php_api/php_api_reference/classes/Ibexa-Contracts-Core-Repository-Values-Content-Query-Criterion-MatchNone.html) is an auxiliary Criterion that returns no search results. It's used internally when no filter or query is provided on a Query object.

The Criterion takes no arguments.
