i have a problem/question to explain:

for example i have 3 documents with the same fields value, so the total score is the same for all docs when i do a search
that match.
i have also some boosts set in bf parameter (boost functions in dismax).

bf = field1^1.0 field2^0.8 field3^0.6

all the fields, except for 1, have values between 1 and 2 so i can control the result score,
but the field1 has unknown value (it can be 1 or 100000).
It is a problem cause i would like to normalize this in a range between 1 and 2 to compare score with the others.

is it possibile? if not is there another way to do this??
Thank you
