That would absolutely help.... then you could use the lucene
QueryParser syntax for boosting:
A query like the following will count matches in the title roughly 10
times as important:
title:Nike^10 review_body:Nike
The dismax handler also has a way of dealing with this (see the Wiki),
and that would be something to explore after you are comfortable with
standard Lucene syntax.
Note that you might want to try spliiting the text into fields and
doing no further boosting--usually the idf and length normalization
factor will give very high scores to title fields without explicit
boosting.
