Exclude some keywords/text during comparison (feature request)

Hey, Markus,

i have some posts with _almost_ duplicated titles and it would be great to exclude some words while comparing.

I will give you example. I have post titles:
a) CarMake1 KEYWORD – Carmodel1
b) KEYWORD CarMake1 – Carmodel1
c) KEYWORD Carmake1 – Carmodel2

Results of searching duplicates now would be like (just as example, not real numbers):
a>b 80%
a>c 80%
b>a 80%
b>c 80%
etc.

But if i would exclude KEYWORD (or maybe couple of keywords) in post titles from calculation, my array becomes this:

a) CarMake1 – Carmodel1
b) CarMake1 – Carmodel1
c) Carmake1 – Carmodel2

And i would see that a and b are 100% dupes and can delete them without checking.

So feature to exclude keywords from calculation of match by titles would be very handy!

Thank you
