Lucene supports boost factors in queries that you construct but I am not
sure if this is available when sine the QueryParser. If you create
the queries yourself, you can definitely achieve that (it is not as
difficult
as it may seem).
Another thing to consider is to prepend the document title to the body you
index.
Possibly (not verified), matches at the
beginning of the document will have higher scoring. This method also
simplifies the searches
since you need to search only in a single field.
