If a filter supports taxonomy filtering and the role has many taxonomies assigned then the resulting search query could look like

(organization_id = 1 OR organization_id = 2 OR organization_id = 3) AND (location_id = 1 or location_id = 2)

However scoped search support using the IN operator, so we could get a more compact query, something along the lines of

organization_id ^ (1,2,3) AND location_id ^ (1,2)
