[Koha] problem in catalog search

[rekhasaraswat]

Hi,
  My name is Rekha saraswat and i m new to KOHA.
  I have got KOHA 3.0  installed on my debian Machine and most of the features are not working fine except catalog search.

The error which is appearing is 
"No record of this type:grs.xml"


 Can any body tell me, what to do?

Regards
Rekha Saraswat
