(In reply to Barton Chittenden from comment #1) > Note that this issue is separate from the URL encoding issues in Bug 13301. Barton, have you tried enabling the QueryParser? I'm more inclined to fix the QueryParser if there are issues with it, and stop spending time on the legacy query parsing code.
I had a customer complaining about this exact issue. Setting UseQueryParser = Try solves it.

This bug is a bit strange and still valid. I can not replicate it on my test instance with master and Zebra or on our 18.11 installation. But it still appears broken on Bywater's installation as linked here. I wonder if it's anything to do with configuration and where to start looking. Switching the QueryParser on is NOT a solution, as we just removed the QueryParser from the code.
