Hi Frank.
It could be the License warning thing.
Just have a look,
Go, Tools/Options/Searching/Basic, it says, "Show License Warning"
Untick the box if you don't want to filter out copyright Files in search results.
This option is enabled at setup, The choice is your decision.
Do a test to see if search results improve.
You can reverse this change at any time, the choice is yours.
P.S. A file that requires a license, is protected so if you obtain a license, that file cannot be shared.
So don't put those files in your shared folder.
That will cause more frustration to others as they play only silence.
