I am experiencing some inconsistent behavior. On one org - I'm doing a SOSL (Search Query) against a custom setting and it works fine. But on a different org - I get entity type My_Custom_Setting__c does not support search.
Did I forget to configure something? I'm not sure why it works on one org and not another. This happens in the developer console - so we are not even talking about code yet. Just a straight SOSL query.
FIND {name} IN ALL FIELDS RETURNING MY_Custom_Setting__c (id, name)
