Tag search does not work at all. Steps to reproduce:
* Add tag #DPP-714
* Search for tag #DPP-714
Expected result: Find the tag I just entered.
Actual result: "No messages matched the search".
Reproducible: Every time at least for about a week and both in Windows client and in web interface.
Text search does not work, either. Steps to reproduce (continuing from previous):
* Search for text "DPP-714"
Expected result: Find the tagged comment I just entered.
Actual result: Hits include the tagged comment, but also some 20 old comments which definitely do not contain "DPP-714"
