Robert Muir commented on LUCENE-5033:
-------------------------------------
Doing an explicit levenshtein calculation here sort of defeats the entire
purpose of having levenshtein automata at all!
> SlowFuzzyQuery appears to fail with edit distance >=3 in some cases

> Levenshtein edit btwn "monday" and "montugu" should be 4. The following
> shows a query with "sim" set to 3, and there is a hit.
> public void testFuzzinessLong2() throws Exception {
> Directory directory = newDirectory();
> RandomIndexWriter writer = new RandomIndexWriter(random(), directory);
> addDoc("monday", writer);
>
> IndexReader reader = writer.getReader();
> IndexSearcher searcher = newSearcher(reader);
> writer.close();
> SlowFuzzyQuery query;
> query = new SlowFuzzyQuery(new Term("field", "montugu"), 3, 0);
> ScoreDoc[] hits = searcher.search(query, null, 1000).scoreDocs;
> assertEquals(0, hits.length);
> }
