SOLVED: JellyCon - Search in Kodi always returns "No results found"

[saviar]

That search button is from Kodi itself, and I believe it only searches Kodi's internal database.  As JellyCon doesn't modify the database, it can't find any results.  However if you go to Add-Ons -> JellyCon -> Add-on Actions -> Search you're able to search the server for specific item types.  Admittedly this is a pretty dumb place for the search to be instead of next to the media itself, but I've genuinely never used the feature until just now when I tested it for this and haven't thought about it.

The log messages from the server are indeed unrelated.  That generally happens when you've replaced or moved a file and the JF database hasn't been cleaned up yet.  They're harmless.

Many thanks for the response. You've completedly resolved the mystery for me and it totally made sense to me now. And yes, the search place for JellyCon is a bit unexpected to me and it'd be nice to be a little bit more intuitive imho, but at least I know where to find it and it's working for me now! 

Also thanks for the explanation about the logs, it's good to know it's unrelated and not a serious problem.
