Unfortunately, there is no clean way to do this. However, you could setup two
databases. One will be a normal one while the second one is greated with a
config file that has the following:

keyword_factor: 10
text_factor: 0
title_factor: 0
heading_factor_1: 0
heading_factor_2: 0
heading_factor_3: 0
heading_factor_4: 0
heading_factor_5: 0
heading_factor_6: 0

This will cause only words in the keyword list to have any weight in searches
and hence matches will be ordered accordingly.

(This is one of the things I want to fix in ht://Dig4, by the way.)
