Would fixing the lengthNorm to 1 fix this problem?
Yes, it would eliminate the length of a field as a factor.
Your best bet is to set up a test harness where you can try out various tweaks to Similarity, but setting the length normalization factor to 1.0 may be all you need to do, as the coord() takes care of the other factor you're after.

I have varying length text fields which I am searching on. I would like
relevancy to be dictated predominantly by the number of terms in my query
that match. Right now I am seeing a high relevancy for a single word
matching in a small document even though all the terms in my query don't
match. Does, anyone have an example of a custom Similarity sub class which
overrides the coord and lengthNorm methods.
Thanks..
