Karl Wettin updated LUCENE-626:
-------------------------------
Attachment: LUCENE-626_20071023.txt
In this patch:
* Updated package javadoc
* Simplified consumer interface with persistent session management :
{code:java}
SuggestionFacade facade = new SuggestionFacade(new File("data"));
facade.getDictionary().getPrioritesBySecondLevelSuggester().putAll(facade.secondLevelSuggestionFactory());
...
QuerySession session = facade.getQuerySessionManager().sessionFactory();
...
String query = "heros of mght and magik";
Hits hits = searcher.search(queryFactory(query));
String suggested = facade.didYouMean(query);
session.query(query, hits.length(), suggested);
...
facade.getQuerySessionManager().getSessionsByID().put(session);
...
facade.trainExpiredSessions();
...
facade.close();
{code}
* Optimizations. On my MacBook it now takes five minutes for the big unit test
to process 3,500,000 queries: training the dictionary and extracts an a priori
corpus by inverting the dictionary of the phrases and words people have most
problem spelling.
* Depends on LUCENE-550 by default again. When it took 30 seconds to execute
100,000 span near queries in a RAMDirectory and less than one second to do the
same witn an InstantiatedIndex it simply did not make sense to use RAMDirectory
as default. Replacing one line of code removes the dependency to
InstantiatedIndex.
* New algorithmic second level suggester for queries containing terms not
close enough in the text to be found in the a priori. Added with lowest
priority and checks against the system index rather than the a priori index.
Soon the second level suggster classes will needs a bit of refactoring.
> Extended spell checker with phrase support and adaptive user session analysis.

> 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
