[Mapserver-users] Use of qstring in CGI itemquerymap

[Steve Lime]

Hi Dan: MapServer experssions are documented in the mapfile guide. It
should be noted that item queries are structured so that you can take
advantage of the underlying RDBMS if one exists. So in reality qstring
is identical in syntax to a layer FILTER. Let us know what the old item
query did and we can help translate to the way things work in 4.0.

I've found plenty of documentation about the new CGI attribute query
techniques in MS 4.0, using qstring.  But all this documentation says
"Query string passed to the query function," or "a valid MapServer
expression, string comparison, regular or logical".

But I can't find any good documentation on what I need to do to get my
itemquerymap working in 4.0 (was working in 3.6).  I can't seem to find
any helpful documentation on MapServer expressions.  

Any help is appreciated,
Dan Martin
