Can I use “OR” logic between facets?

No, when using multiple facets, the choices between them are always compared using AND logic. FacetWP is designed to “filter down”, thus reducing the results.

Using OR logic is possible within individual facets. The following facet types have a “Facet logic” setting, that determines the logic used between multiple choices within the facet:

• Checkboxes
• fSelect
• Range List
• Color

Selecting “AND (match all)” will reduce the results with multiple selections, while “OR (match any)” will increase the results.
