Bug 26957: Don't remove words that are also operators from search terms

FindDuplicate has a hardcoded regex to remove 'and', 'or', and 'not' from any
search fields, however,
is does this with no regard for these terms being embedded in the middle of a
word or phrase.

E.g.:
'Coupland' becomes 'Coupl'
'Frog and toad' becomes 'frog toad'
etc.

This patch simplay removes the substitutions as we already quote the terms as
well

To test:
1 - Add records to your system like:
    The night circus by Erin Morgenstern
    Frog and toad all year
    Nothing ever happens
2 - Attempt to add purchase suggestions like
    title: the night circus, author:Morgenstern, Erin
    title: For and toad all year
    title:nothing ever happens (case is important)
3 - No warnings about existing biblios
4 - Apply patches
5 - Delete existing suggestions
6 - Repeat step 2
7 - Each attempt should warn you of existing biblio
