Karl Wettin updated LUCENE-550:
-------------------------------
Attachment: trunk.diff.bz2
New Patch. Mainly updates in contrib/didyoumean. Merged some core conflicts.
TestGoalJuror now import 200,000 real user queries from a log containing
session id, query, category, timestamp and number of hits, ordered by session
id and time.
This means that the trainer and suggester are not aware of if the user followed
or ignored a suggestion from the system, what results was inspected, if the
query contained a goal, et c. So it does not work as if trained from the start
with the adaptive layer.
Still, the suggester navigates the dictionary fairly well and misspelled
queries will be suggested the correct suggestion, but many correct spelled
phrases will recommend something silly. As one start reporting user
interaction to the suggester any silly recommendation should go away.
In essence, it can only adapt the suggestions positive based on what the
QueryGoalJuror says is a goal. Negative is only when a user don't take a
suggestion. It could be solved with bootstrapping. Will mess with that later.

> An non file centrinc all in memory index. Consumes some 2x the memory of a
> RAMDirectory (in a term satured index) but is between 3x-60x faster depending
> on application and how one counts. Average query is about 8x faster.
> IndexWriter and IndexModifier have been realized in InterfaceIndexWriter and
> InterfaceIndexModifier.
> InstantiatedIndex is wrapped in a new top layer index facade (class Index)
> that comes with factory methods for writers, readers and searchers for unison
> index handeling. There are decorators with notification handling that can be
> used for automatically syncronizing searchers on updates, et.c.
> Index also comes with FS/RAMDirectory implementation.
