Undocumented cardinality search broken

[Jan]

I while ago someone created the ability to make a search like "tags:#3" to find books with at least 3 tags. This search was never added to the manual so I don't know if it's officially available, but using it currently gives me

"calibre, version 0.7.57
ERROR: Unhandled exception: <b>UnboundLocalError</b>:local variable 'loc' referenced before assignment

Traceback (most recent call last):

I would propose to either remove it completely or fix it and add it to the manual
