Filter options

Each filter row includes the following controls:

• Enabled toggle: Turn a filter on or off without deleting it.
• Checkbox: Select the filter row. When one or more rows are selected, additional options will appear:
  • Clone: Duplicate the selected filter row(s).
  • Delete: Remove the selected filter row(s).

Match any vs Match all

Use the Match any / Match all toggle to determine how filters are applied:

• Match any: Returns results that match any of the filters (OR logic).
• Match all: Returns results that match all filters at once (AND logic).

💡 Tip: Use Match any to broaden results, or Match all to narrow down to specific combinations.
