When I select a custom taxonomy on 2.2 Select data to search in, the following message is shown, can you please clarify what is that means – Products & Services are displayed in suggestions only, not in front search results.
Product & Services is a custom taxonomy added to a custom post type in WordPress CMS, I want this field also get indexed and searchable.
On screen 2.2, you can select post types. They will be indexed and searchable on both WP archive pages and WPSOLR suggestions.
But you can also select taxonomies (your “Product & Services”). They will be indexed, but will only be displayed on WPSOLR suggestions. Simply because WordPress archives only display post types, even the so-called “taxonomy” archives (which show post types for a taxonomy term).
