In order to get the correct result you have to make a little change in search.tcl then:
LINE 80: and user_has_row_permission_p ($user_id, 'read', v.version_id, 'FS_VERSIONS') = 't'
has to be changed into
and user_has_row_permission_p ($user_id, 'read', f.file_id, 'FS_FILES') = 't'
I will commit that to SDM...
