Description of problem:
high cpu usage after entering wrong search pattern in RHVM

Version-Release number of selected component (if applicable):
ovirt-engine-4.3.8.2-0.4.el7.noarch

How reproducible:
time to time

Actual results:
sometimes after entering wrong patter into search field ovirt-engine starts consuming too much cpu
it looks like engine keeps trying to seach that invalinf patter even an other search was successfull

could it be possible that it is consequence of https://bugzilla.redhat.com/show_bug.cgi?id=1820980

Expected results:
invalid search will not slow down the manager/ invalid search will be stopped right after the search will fail for the first time and will not occupy engine threads

Steps:
1) Enter wrong search pattern into search field 
2) Check CPU usage and engine logs

Results:
No visible change in CPU usage or overload in logs. Cannot reproduce the issue.

Verified in:
