Also, from the javadocs, check out the explain method on Searcher:
http://lucene.apache.org/java/docs/api/org/apache/lucene/search/
Searcher.html#explain(org.apache.lucene.search.Query,%20int)
As for the state of the documentation, If you have concerns about the
javadocs, please write up an issue in JIRA and, even better, submit a
patch with your improvements. We are always looking for help,
especially in the documentation department. Lucene will only get
better by having people make quality contributions based on their
knowledge of Lucene and IR.

Well, the simplest way is to look at the HITS object returned from
a search.
Something like
Hits hits = searcher.search(new TermQuery(new Term("field",
"value")));
for (int idx = 0; idx < hits.length(); ++idx)
float score = hits.score(idx);
Look at the warnings in the javadoc for why using the Hits object
rather
than a HitCollector is not optimal if you intend to look at more
than 100 or
so documents...

Hello, I am completely new at Lucene. I browsed the web site and the
source code, searching for an example which illustrates the following
operation:
given a Query and a Document, return the score
To me, this is a very basic operation, but I cannot find a class
which
easily provide this functionality.
E.g. the Similarity class provides methods which return the
factors of
the scoring formula, but I would like a method which returns the
score
directly.
Is this possible?
Is the Scorer class the solution? Javadoc is too poor to understand
how to use it. Btw, I do not have an index, I have 1 Document, and 1
Query.
Thanks
