Fuzzy suggester
---------------

                 Key: LUCENE-3846
                 URL: https://issues.apache.org/jira/browse/LUCENE-3846
             Project: Lucene - Java
          Issue Type: Improvement
            Reporter: Michael McCandless
            Assignee: Michael McCandless
             Fix For: 3.6, 4.0


Would be nice to have a suggester that can handle some fuzziness (like spell correction) so
that it's able to suggest completions that are "near" what you typed.

As a first go at this, I implemented 1T (ie up to 1 edit, including a transposition), except
the first letter must be correct.

But there is a penalty, ie, the "corrected" suggestion needs to have a much higher freq than
the "exact match" suggestion before it can compete.

Still tons of nocommits, and somehow we should merge this / make it work with analyzing suggester
too (LUCENE-3842).
