From 94702aa0f07dcea5b7ebe7886b2fdc9ab0092cf4 Mon Sep 17 00:00:00 2001 From: Ludwig Krispenz Date: Thu, 21 Feb 2019 16:54:52 +0100 Subject: [PATCH] Ticket 50234 - one level search returns not matching entry Bug: if in a onelevel search the IDList for the parentid is smaller than the filter threshold and smaller than the list generated by the search filter then the intersection is aborted and all children are returned. Fix: In the above case we need to set the flag that the filter evaluation cannot be bypassed Reviewed by: William, Thierry.
