Use an and/or block to specify conditions that yield a boolean value (**true** or **false**). You form this block by merging multiple conditions or sets of conditions using **and/or** operators.

Use the **operator** field to configure comparison operators in each condition. String comparisons are case-insensitive.

- **is** – Checks if the left side equals the right side.
- **is not** – Checks if the left side does not equal the right.
- **contains** – Determines if the left side string contains the right side as a substring.
- **in** – Verifies if the left side is present within the values on the right side.
- **\<, >, >=, ...** – Applies mathematical operators.

Comparing properties may include catalog properties such as columns, derived columns, blocks, values, or parameters.
