getting [mapetx] from item/value searches

[kenboss]

mapserver is likely simply defaulting to the extent that is defined in your 
mapfile.  To get it to do otherwise, use either the "buffer" or "scale" keywords 
in your query.  Eg.:

http://.../mapserv?map=...&item=place&name=Matatu&qlayer=...&scale=100000
or
http://.../mapserv?map=...&item=place&name=Matatu&qlayer=...&buffer=5000
