mysql querybyattributes

[Skalski Artur - askals]

Can someone point me how to do eficiently querybyattributes on mysql layers using php/mapscript?
 
The layer has over 1 000 000 records (I don't want to split it unless...) can be displayed and queried by point when clicking on map, those things work fast but when it comes to querybyattributes I get error message:
"Execution time of 30 seconds exceded"
 
I know that i can set execution time to 'no limit' but it's no use since user will has to wait that long for each query results.
 
Please help!
 
this is my map file with this problematic layer:
LAYER
     GROUP searchableH
     NAME address
 METADATA
  "DESCRIPTION" "address"
  "RESULT_FIELDS" "ADDRESS"
 END
     TYPE POINT
     CONNECTIONTYPE OGR
     CONNECTION "vdf/address.ovf"
 DATA "address"
     STATUS ON
 PROJECTION
  "init=epsg:4326" #lon/latwgs84
 END
     TEMPLATE "address.html"
     CLASS
         NAME "address"
         STYLE
          SYMBOL 'C:\Inetpub\wwwroot\mapserver\test\etc\pkp.gif'
         END
     END
END
 
and piece of php code that does the query:
 
$qLayer = $gpoMap->GetLayerByName($HTTP_FORM_VARS["SearchedLayer"]);
$qFiled = $HTTP_FORM_VARS["SearchedField"];
$qValue = strtoupper($HTTP_FORM_VARS["SearchedValue"]); 

  $qLayer->queryByAttributes($qFiled, $qValue, MS_MULTIPLE);
 
what can be wrong???
 
Best Regards
