Eks Dev commented on LUCENE-3846:
---------------------------------
Sure, give me enough annotated data and I can give you "close to optimal" cost
matrix. There are (rather simple) ways to estimate these costs.
Or you are trying to argument there is no cost table better than the one filled
with ones?

> 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).
