-------------------------------------
Attachment: LUCENE-1297.patch
Attaching a new version (only added ASL 2.0 to StringDistance + typo fix)
Question (why - what does it do?) about this TRStringDistance change:
- return p[n];
+ return 1.0f - ((float) p[n] / Math.min(other.length(), sa.length));
> Allow other string distance measures in spellchecker
