RE: searching multiple fields

Hello,I'm not sure if it's the smartest solution, but if
your request go throught a programming layer, you could
rewrite it using regular expression :
query="apple" is rewrited in
query="title:apple AND text:apple", for example.
Don't know if it's clever performancewise, but it works
fine, although I would love to use a more integrated
solution...Here what i do, in php :    private function
parseQuery( $query ){        $reservedWords = array( 'and',
'or', 'not' );        $operator = '+|-';       
$completion = '*?~';        if (
sizeof($this->searchFields)>0 ){
//$this->searchFields = fields to be searched for        
   if ( preg_match_all( '#('.$operator.')?(bw+b?(([^>]
*)|"[^"]*"|bw+[w'.$completion.']*b['.$co
mpletion.']?)#', $query, $matches, PREG_OFFSET_CAPTURE ) ){ 
              // $matches : 0=>complet : 1=>operator ;
2=>field ; 3=>term / 0=>value 1=>offset         
      $newQuery = $query;                for (
$i=sizeof($matches[0])-1; $i>=0; $i-- ){                 
  if ( !in_array( strtolower($matches[3][$i][0]),
$reservedWords ) and !$matches[2][$i][0] ){                 
      if ( $nbField=sizeof($this->searchFields) ){       
                    $term =
$matches[1][$i][0].(($nbField>1)?'(':'');                
           foreach ( $this->searchFields as
$key=>$field ){                                if
($key>0) $term .= ' OR ';                               
$term .=
"(".$field.":".$matches[3][$i][0]."
)";                            }                       
    $term .= (($nbField>1)?')':'');                      
     $query = substr_replace( $query, $term,
$matches[0][$i][1], strlen($matches[0][$i][0]) );           
            }                    }                }         
  }        }        return $query;    }Hope this can
