Expand Filter Criteria Operators List?

[McFateM]

We've recently built some relatively sophisticated Solr collection views in Digital Grinnell, but just found that one family of views is not working as we expected. The issue is with objects that are shared between two or more collections. It appears the issue is in our views' Filter Criteria where we enforce a clause like this:

Islandora Solr: RELS_EXT_isMemberOfCollection_uri_s (= info:fedora/grinnell:kleinschmidt)

However, what I really need is a clause like this:

Islandora Solr: RELS_EXT_isMemberOfCollection_uri_ms (Contains info:fedora/grinnell:kleinschmidt)

Unfortunately, the only available operators in these filter criteria appear to be "Is equal to" and "Is not equal to".

Any idea how/where I can add a "Contains" operator to the available filter criteria? Thanks.

Unless I'm misreading (its happened before!) you should be okay with using RELS_EXT_isMemberOfCollection_uri_ms instead of

RELS_EXT_isMemberOfCollection_uri_s.

The single valued field won't return all applicable values but the multivalued will.

Thanks for the quick reply Alan. I tried that earlier but failed because our Solr schema slurps so much and creates so many fields I could never get my change to post properly. I will try making the change in code and see what happens instead.

It works! Changed my views in code to reference RELS_EXT_isMemberOfColleciton_uri_ms instead of ...uri_s, and as Alan indicated, it works properly. I had no idea that Solr multi-valued fields would work like this in a "Is equal to" relationship.

Closing this issue as resolved. Thanks all and take care.
