Robert Muir resolved LUCENE-2557.
---------------------------------

Resolution: Duplicate

Duplicate of LUCENE-124, which added this new rewrite method in trunk and 3.x:

{noformat}
* LUCENE-124: Add a TopTermsBoostOnlyBooleanQueryRewrite to MultiTermQuery.
This rewrite method is similar to TopTermsScoringBooleanQueryRewrite, but
only scores terms by their boost values. For example, this can be used
with FuzzyQuery to ensure that exact matches are always scored higher,
because only the boost will be used in scoring.
{noformat}
FuzzyQuery - fuzzy terms and misspellings are ranked higher than exact matches

Key: LUCENE-2557
URL: https://issues.apache.org/jira/browse/LUCENE-2557
Project: Lucene - Java
Issue Type: Bug
Components: Query/Scoring
Affects Versions: 3.0.2
Reporter: Jingkei Ly
Attachments: idf-scoring-test-case.patch


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".
