Robert Muir commented on LUCENE-2557:
-------------------------------------
In the example of the link, I'm still lost as to why its really useful.
If all queries are prefix queries, what is the use case for that? Maybe really
what is needed is
suggester, stemming, decompounding, or some combination of those?
If its really some unique use case that isnt one of the above, and every query
must be a prefix query,
at least bake it in with edge-ngrams filter at index time for better
performance. (and just use termquery)
> FuzzyQuery - fuzzy terms and misspellings are ranked higher than exact matches

> Project: Lucene - Java

> 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".
