How to select multiple values for Drupal Facets (Facet API + Search API) I am using Facet API + Search API to develop Filtering for the data within my site. I am also using Ajax Facet Filters to process the selection as soon as it's clicked.

It all came out great but there's one slight problem. I can only select one option per category. As soon as I select an option, all the inactive options hide and only the active (clicked one) shows.

I want the option to select multiple option but with my settings of Facet API &amp; Search API, there seems to be no option.

Here's the picture to explain.


I'll be very thankful for any assistance.

Best.

I found the first comment here to answer this question.


  the OR operator is required for the facet instead of the default AND.
  If the implementing search module you are using supports OR facets,
  you will have an option in the "Global settings" fieldset located in
  the bottom left hand corner of the facet's display settings form.
