Define rules to control data flow in pipelines. Filter component configuration panel ## Conditions ### Logical operator By default, a record must match all the conditions. Logical operator selection for filter conditions * **Match all of the following conditions (AND)** - selects records with values that meet all conditions specified (logical "AND") Match all conditions AND operator example * **Match any of the following conditions (OR)** - selects records with values that meet at least one of the conditions specified (logical "OR") Match any condition OR operator example * **Match none of the following conditions (NOT)** - selects records with values that doesn't meet any of the conditions specified (NOT ( ... OR ... )) ### Specifying conditions Each condition comprises of an expression (or field), a comparison operator, and possibly another value or expression to compare with (depending on the operator). * **Expression (left-hand)** - In the dropdown list on the left, select a field or edit an expression. (You can read more about [expressions](/docs/etl/using-expressions-in-integrateio-etl/) and [functions](/docs/etl/integrateio-etl-functions/)) * **Operator** - Select the operator from the following list: | Operator | Description | | :- | :- | | text equals | The expression on the left must be equal to the string value on the right. The text should not be enclosed in quotes or escaped. | | text not equals | The expression on the left must not be equal to the string value on the right. The text should not be enclosed in quotes or escaped. | | text matches | The expression on the left must match the regular expression string value on the right. The text should not be enclosed in quotes or escaped. For example, matching a string field with .\*dog.\* would pass any string that contains the string dog: dog, dogs, adogmatic. | | text is empty | The expression on the left must be empty. | | text is not empty | The expression on the left must not be empty. | | = | The expression on the left must be equal to the expression on the right. | | != | The expression on the left must not be equal to the expression on the right. | | > | The expression on the left must be greater than the expression on the right. | | >= | The expression on the left must be greater than or equal to the expression on the right. | | `<` | The expression on the left must be less than the expression on the right. | | `<=` | The expression on the left must be less than or equal to the expression on the right. | | is null | The expression on the left must be null. | | is not null | The expression on the left must not be null. | | is true | The expression on the left must true - especially useful when left hand side is a complex expression. | * **Value/Expression** - with text operators, type the text or pattern to compare to. With other operators, pick a field or edit an expression. ## Related This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
