Therefore, it is crucial for the index-only plan that a secondary-index search generates the final (trustworthy) result for the given search. By nature, a non-enforced index casts a numeric value when if the type between the given value and the type of the index are different. Therefore, a search on a non-enforced index may generate a super-set of the final result. So, we need to find a resolution - 1) non index-only plan on the non-enforced index at all, 2) a partial application of index-only plan -- This message was sent by Atlassian JIRA (v6.4.14#64029)
