Finally someone posted me the solution. I post the solution to my own question because i think someone may have similar problems
Install the Microsoft Filter Pack 2.0
than
EXEC sp_fulltext_service 'update_languages';
EXEC sp_fulltext_service 'load_os_resources', 1;
EXEC sp_fulltext_service 'restart_all_fdhosts';
After installing the filters, run this to refresh the list. EXEC
sp_fulltext_service 'update_languages';
You will also likely need to refresh the filters and restart the FTS
service launcher: EXEC sp_fulltext_service 'load_os_resources', 1;
EXEC sp_fulltext_service 'restart_all_fdhosts';
Finally, you’ll need to do a complete rebuild/refresh of any existing
full-text indexes (see ALTER FULLTEXT INDEX) to use the new filters.
