More information
When Relevanssi processes query variables, it converts them to MySQL query restrictions. This filter hook lets you modify the MySQL query for post type parameters.
The post type parameter becomes MySQL code that filters posts based on post type, both for inclusive and exclusive post types, and considering the users and taxonomy terms that don’t have a post type (or a post ID).
