-----------------------------------------

Hi C=C3=A9drik.  Yes, please open a new issue and attach the patch if you h=
ave it.  It looks like this would create a commons-lang dependency, in whic=
h case the build script for the spell checker might need a small tweak, too=
.

> 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:
> =20
> 3start:
> 4start:
> ..
> 3end:
> 4end:
> ..
> transposition:
> =20
> This index is a dictonary so there isn't the "freq" field like with DSc v=
ersion.
> it's independant of the user index. So we can add words becoming to sever=
al
> 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 sp=
ecific
> 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.
> =20
> See the test case.
