Filter Based on Relationship Field Titles Within 2 Collections?
Hey,
We are using Low Search with a filter dropdown which points to the Title of a parent relationship field (a channel with People/members based on Zoo Visitor). The search is based on 2 collections, but the relationship filter requires a child field parameter... which means that when the user makes a relationship selection the search only searches within the collection/channel which the relationship filter field is from.
Is there a way to make the search show results from two collections (instead of one)?
See attached code screenshot.

I'm afraid that's not possible at the moment. All parameters are cumulative, so filtering by (Collection A) OR (Collection B AND Child = X) is not possible.
I can't really see how, in LS's setup, this can be done, other than a custom filter.

I see. It would be (Collection A AND Child X) OR (Collection B AND Child X) in the same search (the user is only selecting the child, LS searches in all collections by default... But I assume this still cannot be done (without a custom filter)?
Thanks!

If the relationship field is the same for both collections (ie. they share a field group), then that's possible. If the fields are different, then combining them with OR is not possible without a custom solution.
