Dear Maintainer,

After upgrading cmus, the search box no longer finds strings included in
file names, as previous versions did.  There appears to be no setting to
restore that behaviour.  This makes it difficult to find certain tracks;
for example, those tagged in non-Romanised Japanese, which I cannot read
or type.

Some setting to control the fields to search would be useful.  Or maybe
it could automatically search file names when they're displayed (as I've
configured the library view to do).
