> hy,
> i developed a SpellChecker based on the David Spencer code (DSc) but more flexible.
> the structure of the index is inspired of the DSc (for a 3-4 gram):
> word:
> gram3:
> gram4:
>  
> 3start:
> 4start:
> ..
> 3end:
> 4end:
> ..
> transposition:
>  
> This index is a dictonary so there isn't the "freq" field like with DSc version.
> 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.
> 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.

> i hope this code will be put in the lucene sandbox.
