[Mapserver-users] Indexquery

[John Rubin]

Is it possible to query a polygon only within the present map extent?

I have 20 county tile indexed shapefiles which contain forest polygons.  In the attributes of these shapefiles is a unique code for each polygon  which contains a mapsheet number and a stand number. 
An itemquery is too slow for the number of polygons.  
I can determine the tileindex of the county number by the mapsheet number.  I suspect an indexquery would speed up the process.  Can anyone give some advice or example on how to use an indexquery?

Yours truly
