Guide search, doesn't show much

What is the Channels DVR Guide Search checking when u search? It does not find anything I am looking for, shows that have that word in its show title, episode name, or synopsis. Its rather useless.

I recently loaded up Emby via m3u, which i used to use for TV way before Channels, and it now populates its guide for the channels i have.
When I use their search, it pulls up all the programs that will air that I am looking for and want to possible record.

Example. I search for "tiger". I want to see what programs air that have anything to do with tigers, the animal not the sports teams. Channels shows practically nothing, whereas Emby show many programs.

This morning I tried to search the guide (web browser) for "ReliaQuest" without quotes to find the Badger football game tomorrow on ESPN2. It doesn't find it, but I was able to find it by spending some time looking the guide over manually - it's a bit strange how the user moves forward in time in the guide in a browser. Then I tried using the browser's own search when I finally had the guide scrolled properly, and that found it.

I guess I'd also be interested to know a little more about how the Channels DVR search field works in the browser, or doesn't work.

For the record, if Channels DVR finds the "ReliaQuest" bowl too obscure, that would be understandable after this year's Badger performance.
