Hi,
I am a newbie here. I just downloaded the trial version. I tested the search feature to help me clean up tags and while searches like "www has \_\_" (\_ is a placeholder) work just fine (same with a bunch of other tags), "contentgroup" returns no file although if I display the extended tags, I see contentgroup.
- I also tried with "has "m" to trigger on one letter).
- I also changed the contentgroup to "foo" and then searched (to eliminate an invisible character in the tag).
These are Flac files.
Am I missing something or is this a (know) bug?
thank you.

Can you post a screenshot of Extended Tags and the filter query you tried to match the track?
There are no know issues with the Filter expression language.

Please note that the / a filter keyword has to be written in capitals: HAS
