Negative boosts are accepted, though rather "unusual". Also note that
Lucene by default filters out any hits with scores <= 0.0.
Normally you'd set boost to something > 0.0 (0.1 should work).
What unexpected effect are you seeing?
If you omit norms, then indeed your per-doc boost (and per-field
That was my problem... I was ommiting norms, so the boost I gave at the
document at index time was not taking effect.
Since I stop omitting them results have changed completely.
Thanks!

Hi,
I have the following situation which needs to customize the final score
according to field value.
Suppose there are two docs in my query result, and they are ordered by
default score sort:
doc1(field1:bookA, field2:2000-01-01) -- score:0.80
doc2(field1:bookB, filed2:2009-01-01) -- score:0.70
Do you want the dates to *influence* or *determine* the order? I
don't have much help if what you're after is something like "docs
that are more recent tend to rank higher", although I vaguely
remember this question coming up on the user list, maybe a
search of the archive would turn something help
Hi All,
Sorry for the confused email.
Suppose I have a field text with content below
KeyWordAnalyzer is a class. this keyword is used in java.
Here the KeyWordAnalyzer into Key Word Analyzer and class should be a Key word.
So if some one search. Apart from this I want Key Word Analzer to tokeni

H. There's nothing in Lucene that I know of that will do what you
want, you'll have to do one of two things:
In general, you'll have to break up your token stream yourself, either
through pre-processing or building your own analyzers. There's
nothing already built that I know of that will brea
Karl,
Thankyou for your in-depth reply. This has given me good grounds to go on.

You might want to play with both boosting and multiple sorting.
You might want to look at something like Solr's boost queries or boost
functions

Or if you want to go down the path of a custom score, most
Here is my code for indexing:

String indexFilepath = args[1];

IndexWriter writer;

Well, nothing jumps out at me, although I confess that I've not
used MultiFieldQueryParser. So here's what I'd do.

MultiFieldQueryParser for instance. Get the really simple case
