   * 1. More field types: Includes 'text', 'multi-select', 'date', and 'boolean'.
   * 2. Enhanced flexibility: Allows for more precise and varied filtering options.
   * 3. Used with DataTableAdvancedToolbar: Enables a more sophisticated filtering UI.
   * 4. Date and boolean types: Adds support for filtering by date ranges and boolean values.
