What's the saying? "It's not a bug, it's a feature!"
The QueryConverter is by definition a simple implementation that
handles the basics and is designed to be replaced by those with
specific needs. http://wiki.apache.org/solr/SpellCheckComponent#head-8a3a4d45708be416cec61a9387131cd52fcdbbbf
It would probably be good to at least have a few different
implementations for handling various common scenarios.

Hi,
We think it may have a bug with the spellchecker. It is about
accents
and ISO-latin special characters. If I'm doing a request like this
(about
the word "considération") :
http://localhost/solr/spellCheckCompRH?q=considération&spellcheck=on&spellcheck.dictionary=file
and if I have a good amounts of words in my dictionary, it will return
suggestions for "consid" and "ration". It look likes it's
considering the
"é" character as a space or a separator.
Having looked through the code, I have found the class
SpellingQueryConverter which seems to do the work. I think that the
problem
is the regular expression : the predefined character class \w might
not work
for special characters. As defined by the Java API, \w = [a-zA-
Z_0-9], which
could not necessarily include ISO accent characters. I didn't found a
regular expression that would be able to work all this out, but I
think that
it would be important to fix that for the next version.
The version we're working with is the Nightly Build of 2009-03-04
(because
we need the better tuned-up facet module, which is quite faster).
Thanks.
