Unfortunately I'm not sure what boosting capabilities were available
in 1.2, but that syntax is correct for the 1.4+ at least.
And I'm sure the Explanation feature is not available in 1.2, but
with more recent versions of Lucene you'd be able to see the effect
of the boosts on the score.
Does Query have a setBoost() in 1.2? If so, maybe the parser didn't
support boosts at that time? Sorry I'm not of more help.

Is there a way to boost a token while querying? Example, in the
following query +(DESC:sheets DESC:sheet), can the token 'sheets' be
boosted and given higher precedence over 'sheet' so the results
matching
'sheets ' appear before those for 'sheet'? I am using lucene 1.2. I
tried using the boost factor for 'sheets' so the query would read:
+(DESC:sheets^2.0 DESC:sheet), but that did not help.
I have read overriding getFieldQuery of QueryParser would help boost
terms/tokens, but this is not available in lucene 1.2. Nor is the
IndexSearcher's explain method.
Any ideas on how this can be accomplished?
Thanks.
