You can define how multiple selected filters are combined on a Quick Controller using the following options:

Combine Filters options
  • “AND”: only show issues matching all the selected filters.

    • Example: display issues that are bugs and are in progress.

  • “OR”: only show issues matching any of the selected filters.

    • Example: display issues that are either bugs or have a high priority.

  • “Do not combine filters”: only one filter is active at a time. Every time a filter is selected, the previously selected filter (if any) is disabled.
