Spell check functionality needed
--------------------------------

                 Key: HSEARCH-269
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-269
             Project: Hibernate Search
          Issue Type: New Feature
          Components: engine, mapping
    Affects Versions: 3.2.0
            Reporter: John Griffin
            Assignee: John Griffin


>From Emmanuel:
 - more than one field and even more than one index should be the source of the dictionary
 - declaring which field is part of a dictionary should be declarative @AddToDictionary(name="main-dictionary") 
   (with probably an optional field name(s))
 - for a given dictionary name, we need to associate an index and probably a field prefix (to share the same index 
   for all dictionaries). This couold be by annotations or in the configuration (not sure)
 - this index should be kept like any other DirectoryProvider in the HSearch intrastructure (we could then reuse 
   ReaderProvider internally and don't have leaks). 
 - we will probably add a manual dictionary reindex method and the SpellChecker API should be in the SearchFactory. 
    sf.getDictionary("main-dictionary").spellcheck(word, suggestion);
    sf.getDictionary("main-dictionary").spellcheck(word, suggestion, entity, properties...); //not sure how useful is this one really
    sf.getDictionary("main-dictionary").reindex();

this needs to be refined.
