issue: 2023
title: "The JPA server maintains a cache of active SearchParameeter resources that can cause misleading results
if a SearchParameter is changed and other resources that would be indexed by the changed SearchParameter are updated
before the cache refreshes. A new interceptor has been added that should force a refresh sooner, especially on
non-clustered systems."
