+---
+
+# Custom Field Criterion
+
+The [`CustomField` Search Criterion](/api/php_api/php_api_reference/classes/Ibexa-Contracts-Core-Repository-Values-Content-Query-Criterion-CustomField.html) searches for content or locations based on the contents of the search index fields.
+
+The allowed syntax and operator support might differ between search engines and the type of queried field.
+
+## Arguments
+
+- `target` - string representing the identifier of the search index field
+- `operator` - one of [Operator](/api/php_api/php_api_reference/classes/Ibexa-Contracts-Core-Repository-Values-Content-Query-Criterion-Operator.html) constants
+- `value` - the value to query for
+
+## Limitations
+
+The `CustomField` Criterion isn't available in [Repository filtering](search_api.md#repository-filtering).
+
+## Example
+
+### PHP
+
+``` php
+[[= include_file('code_samples/search/content/customfield_criterion.php') =]]
+```
