Description

Extensive javadocs available in patch, but I also try to keep it compiled here: http://ginandtonique.org/~kalle/javadocs/didyoumean/org/apache/lucene/search/didyoumean/package-summary.html#package_description

A semi-retarded reinforcement learning thingy backed by algorithmic second level suggestion schemes that learns from and adapts to user behavior as queries change, suggestions are accepted or declined, etc.

Except for detecting spelling errors it considers context, composition/decomposition and a few other things.

heroes of light and magik -> heroes of might and magic
vinci da code -> da vinci code
java docs -> javadocs
blacksabbath -> black sabbath

Depends on LUCENE-550
