Allow shapeindex in mapserver expressions
[shapeindex] (or [shpidx] or [recno]) should be allowed in mapserver
expressions to allow query on multiple shapeindices. Here is my original mail
to the mapserver-users list, and Stephen Lime's answer:

Emne: Re: [Mapserver-users] INDEXNQUERY
The best way to implement would be by allowing you to query by index.
That is treat the index as a normal column in MapServer expressions.
That way you'd just use the itemquery and itemnquery modes. That's a
lot easier to add then a totally new query mode.
Please file this as a feature enhancement and I'll add it to 3.7.

Hi all,
What I really would like is the INDEXNQUERY mode. This would allow me
to
find and display multiple shapes by index. However, this does not
exist.
I guess I could achieve the same result with a filter, but I am afraid
that performance wouldn't be up to standards.
Does anyone have a suggestion regarding how to implement this? I am
normally using PERL mapscript for advanced purposes, but I would
prefer
a normal CGI solution.
