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).
