Problem with searches

 
Hi,

I have a problem with searches in my Jahia site. In my production Jahia site
(Jahia + Apache), searches are ok, but in the one that is installed in the
client (Jahia 4.0.6 + WebSphere + Oracle) general searches always return "0
elements found".
 
This is the log of the server. It seems that a index called _1o3.fnm is not
present. Maybe this can be the problem? How can I solve it?

Thank you in advance for your help.

Alex.
