A little (big?) problem.
Calibre on old pc. Using 1.2GB of mem! on a special search
Error removed from clipboard on killing calibre

Used the plugin on db known by kiwidude
I exempt the large list of duplicates (also known by kd)

used:
Title soundex 8
author similar
Show all groups
Sort groups by number of duplicates
Calibre mem size on start: 130mb
So mem expanded about 10 times.
After closing error, calibre was still open, mem did not decrease.

EDIT:
while ctrl + \ was lost. I added \ as next-shortcut
