Yes, but not quite. The 'TILEINDEX' keyword tells mapserv that a an 
index-shapefile exists that references a proviously tiled dataset. And to use 
that index-shapefile during mapconstruction to achieve faster mapping like 
you described. 

You must tile your dataset and create the index-shapefile beforehand. For 
tiling look in the wiki VectorHOWTO and check the utility programs 'tile4ms' 
and 'shp2tile'.
