```
[Mon Aug 11 07:23:46 2014] [error] [client 10.35.188.159] File "/var/www/vhosts/mf-chsdi3/private/chsdi/chsdi/views/search.py", line 113, in _swiss_search
[Mon Aug 11 07:23:46 2014] [error] [client 10.35.188.159] temp = self.sphinx.Query(searchTextFinal, index='swisssearch')
[Mon Aug 11 07:23:46 2014] [error] [client 10.35.188.159] UnboundLocalError: local variable 'searchTextFinal' referenced before assignment
