Fix find -v command on tables (issue #9043) (#9159)

Browse Source 
# Description
This PR fixes issue #9043 where find -v was returning empty tables
and/or wrong output.
It also refactors some big code chunks with repetitions into it's own
functions.

# User-Facing Changes

# Tests + Formatting
Unit tests added for asserting changes.
