Finding duplicate fixlets

I’m trying to come up with session relevance to identify duplicate content in our environment. If I go with looking for duplicate names like this:

( it, multiplicity of it) of unique values of names of bes fixlets whose (custom site flag of site of it and (fixlet flag of it OR task flag of it OR baseline flag of it) )

I can get pretty close. Problem is users will occasionally change the name slightly depending on which custom site the content resides.

So then I was thinking maybe I could look for duplicate relevance. I’m trying to do something like this

(
concatenation “|” of names of bes fixlets whose (relevance of it = stuff from below )
)
of
(
(unique values of relevances of bes fixlets whose (custom site flag of site of it and (fixlet flag of it OR task flag of it OR baseline flag of it) ))
)

Anyone have any ideas?
