[SM-USERS] "Search" functionality does not work

[klag]

HI,

When i start a search in SM with the word "test" in this exemple, i've got the error message below :

ERREUR : Impossible d'achever la requête (impossible to achieve the query).
Requête (query): SEARCH CHARSET "US-ASCII" ALL FROM {4} test
Raison invoquée : Not implemented yet

The language of SM is french but i've tested with English language and the problem is similar.
My default_charset is iso-8859-1 and lossy_encoding is false.
To finish, my SM version number is 1.4.4

I wish you could help me.
Thanks,
