sql error on search

Hi,

after installation (with sql manual update as written on notes) and configuration of the latest version (I build a view vith some filters on), upon a search, I obtain this error:

user warning: Table '

.temp_vfs' doesn't exist query: SELECT count(node.nid) FROM node node INNER JOIN temp_vfs temp_vfs ON node.nid = temp_vfs.nid LEFT JOIN content_type_articolo node_data_field_data_pubblicazione ON node.vid = node_data_field_data_pubblicazione.vid LEFT JOIN term_node term_node ON node.nid = term_node.nid LEFT JOIN term_data term_data ON term_node.tid = term_data.tid WHERE (node.status = '1') AND (( REPLACE(node_data_field_data_pubblicazione.field_data_pubblicazione_value,'T',' ') + INTERVAL (3600) SECOND) <= (NOW() + INTERVAL (3600) SECOND)) AND (node.type IN ('articolo')) AND (term_data.vid = '1') in \includes\database.mysql.inc on line 172.

Any ideas?

Many thanks in advance,
