Resolution: Not A Problem

For Lucene, LUCENE-2089 will always be faster than even FastSS, as our FuzzyQuery is really a top-N query, and we can exploit properties of the priority queue to make it even faster.

LUCENE-2089 also works without any auxiliary index or data structures, just solely on lucene's terms dict, so it works great for updates/NRT/whatever, no back compat problems.

I'm cancelling this issue as the alternative is superior in every aspect.

Key: LUCENE-1513
URL: https://issues.apache.org/jira/browse/LUCENE-1513
Project: Lucene - Java
Issue Type: New Feature
Components: contrib/*
Reporter: Robert Muir
Priority: Minor
Attachments: fastSSfuzzy.zip


code for doing fuzzyqueries with fastssWC algorithm.
FuzzyIndexer: given a lucene field, it enumerates all terms and creates an auxiliary offline index for fuzzy queries.
FastFuzzyQuery: similar to fuzzy query except it queries the auxiliary index to retrieve a candidate list. this list is then verified with levenstein algorithm.
sorry but the code is a bit messy... what I'm actually using is very different from this so its pretty much untested. but at least you can see whats going on or fix it up.
