# ProductAvailability Criterion

ProductAvailability Search Criterion

The `ProductAvailability` Search Criterion searches for products by the availability flag, the boolean value set per product or variant.

To search for products that can be ordered, recreate the availability conditions with [existing product search criteria](https://doc.ibexa.co/en/latest/search/criteria_reference/product_search_criteria/index.md), for example [LogicalAnd](https://doc.ibexa.co/en/latest/api/php_api/php_api_reference/classes/Ibexa-Contracts-ProductCatalog-Values-Product-Query-Criterion-LogicalAnd.html), [LogicalOr](https://doc.ibexa.co/en/latest/api/php_api/php_api_reference/classes/Ibexa-Contracts-ProductCatalog-Values-Product-Query-Criterion-LogicalOr.html), and [`ProductStock`](https://doc.ibexa.co/en/latest/search/criteria_reference/productstock_criterion/index.md). To recreate complex [custom availability strategies](https://doc.ibexa.co/en/latest/product_catalog/create_custom_availability_strategy/index.md), you might need to implement [custom search criteria](https://doc.ibexa.co/en/latest/search/search_criteria_and_sort_clauses/#custom-criteria-and-sort-clauses) for the conditions not covered by the built-in ones.

For more information, see [Availability and computed availability](https://doc.ibexa.co/en/latest/product_catalog/products/#availability-and-computed-availability).
