SpellChecker

a Spell Checker allow to suggest a list of words close to a misspelled word. This implementation use the n-gram technic and the levensthein distance. 
A  Index (the dictionary) with all the possible words (a lucene index) must be  created. The structure of this index is (for a 3-4 gram):
word:
gram3:
gram4:
3start:
4start:
3end:
4end:
transposition:
 
it's independant of the user index. So we can add words becoming to several
fields of several index for example or, why not, to a file with a list of words.

source:

SpellChecker spellChecker= new SpellChecker();


The suggestSimilar method return a list of suggests word sorted by the
Levenshtein distance and optionaly to the popularity of the word for a specific
field in a user index. More of that, this list can be restricted only to words
present in a specific field of a user index.
 
See the test case code for example
