Subject: CFSEARCH, Verity, Scoring

Using MX 6.1...I have a question regarding scoring in verity.  First a
little background:

According to Mac docs, STEM and MANY are modifiers that are the default
behavior of the CFSEARCH command (if you do not specify any other
modifiers).  This is what allows us to get a 'score' result giving us a
'relevancy' ranking of the results.  The Mac docs state that STEM causes
similarly stemmed words to come up in the results (e.g. if you search on
'instructs', your results will also include words like 'instructional',
instruction', etc.).  

Currently, the score is based on the number of occurrences of the search
criteria in a document.  The more times it occurs in a document, the higher
the score.  However, since we are using a STEM modifier, it's not just the
exact criteria that is used to determine the score, it's anything with the
same STEM.  So, there exists the possibility, if not probability, that a
document with 4 occurrences of the word 'instructional' would have a higher
score than a document with 2 occurrences of the word 'instructs'.  

This is part of my problem.  Our client wants the benefits of STEM
(including multiple similar terms in the search results) but wants documents
with the 'actual' criteria scored HIGHER than documents just having STEMS of
the criteria.

Is this possible, and if so, how would you do it?  My thinking is that the
only thing we could do is take the results from CFSEARCH and manipulate them
manually to change the scores, but that would be a huge hit on processing.
I really need to know if you can do this somehow with modifiers in Verity
that we can pass through the CFSEARCH interface.

Thanks!

Dave
