Subject handling different scores related to queries
Date Tue, 27 Nov 2012 17:38:22 GMT
for a search string hello*~ how the scoring is calculated?

as the formula given in the url:
http://lucene.apache.org/core/old_versioned_docs/versions/3_0_1/api/core/org/apache/lucene/search/Similarity.html,
doesn't take into consideration of edit distance(levenshtein distance) and
prefix term corresponding factors into account.

Does lucene add up the scores obtained from each type of query included i.e
for the above query actual score=default scoring+1/(edit distance)+prefix
match score ?, If so, there is no normalization between scores, else what
is the approach lucene follows starting from seperating each query based
identifiers like (~(edit distance), *(prefix query) etc) to actual scoring.
