-------------------------------------
I think you are missing point here whilst there may be some way I can achieve
my aim by changing indexing (heres an only slight outof date example using the
actual code
http://svn.musicbrainz.org/search_server/trunk/servlet/src/main/java/org/musicbrainz/search/servlet/DismaxQueryParser.java)
the fact is that it doesn't make sense to fully score fuzzy queries if your
query contains exact and fuzzy matches (the current default), and it doesnt
make sense to use a constant score either (your suggestion), a default that
does score but uses the idf of the search term would give much better default
results.
> FuzzyQuery - fuzzy terms and misspellings are ranked higher than exact matches

> The FuzzyQuery often causes misspellings to be ranked higher than the exact
> match, which seems to be an undesirable property generally.
> For example, in an index of surnames, if I search using a FuzzyQuery for
> "smith", the misspellings such as "smiith", or "smiht" would appear near the
> top of the search results ahead of documents that match "smith".
