I'm trying to use both CQL_FILTER (to add spatial constraints) and
MAXFEATURES in a WFS GetFeature request. A query with:
SERVICE=WFS&VERSION=1.0.0&REQUEST=GetFeature&CQL_FILTER=INTERSECT(geometry,POINT(98.232999999946
29.115999999383))
returns results as expected.
Once I add &MAXFEATURES=1, though, no results are returned. This continues
through about MAXFEATURES=500. At MAXFEATURES=600, one result begins to be
returned, and when I jump to MAXFEATURES=10000, many results are returned.
Shouldn't MAXFEATURES=n return n results? Is the MAXFEATURES constraint
applied before CQL_FILTER, or am I missing something about how this is set
up? I don't have access to the GeoServer backend, so I unfortunately can't
look at the queries that are being performed.
Strange, i seem unable to replicate this behavior. Do you know what kind of datastore is being queried in the back end? Also which version of GeoServer are you using.
A shot in the dark, but one thing might be to try to rearranging the order of the parameters. Put the maxfeatures param before the cql_filter param.

Tom,
Also, what happens if you remove the INTERSECT and just have MAXFEATURES? Does it return n? Or if you can’t do that because INTERSECT is required (I don’t know much about CQL ), try replacing it with WITHIN, DISJOINT etc.

Thanks for the help. I know that this is running off a PostGIS database,
but I'm not sure how to find what version of GeoServer it is. Is there a
request that will return that?
Reordering the params unfortunately doesn't change the outcome, nor does
switching in something like CONTAINS for INTERSECT.
If I remove the CQL_FILTER param and keep MAXFEATURES=n, n results are
indeed returned.
I might be able to contact the person who maintains this copy of GeoServer
to see if he can help, but if anyone has any other ideas, that'd be great.
Thanks,

If you go to http://<host>:<port>/geoserver/welcome.do it should tell you what version of geoserver you are running. Knowing it is postgis might help, i will try to reproduce. Any chance you can provide a bit of the data that is in the database, as it could possibly be a data issue.

Unfortunately I am not able to replicate the issue with GeoServer 1.7.5, so it could just be that this is an issue that has been solved. But basically I added the shapefile you send and executed the following:

Thanks for taking a look at this. I'm using a workaround now that mitigates
this a little but doesn't solve it. I think we might just use that until
we're sure that we need a fix for this, and if we are, we'll ask the person
who maintains our copy of GeoServer if he could take a look.
