Hi Jukka,
I see what the difference is after some testing. Using the exact same URL
but only changing the WFS version:
http://wppgeog3/geoserver/ows?service=wfs&version=2.0.0&request=getfeature&typename=Public_Data_DB:OS_ADDPOINT_WSHIRE&resulttype=hits
WFS 1.0.0 - 0 (wrong)
WFS 1.1.0 - 7500 (correct)
WFS 2.0.0 - 0 (wrong)
Looking in the spec, 1.0.0 doesn't seem to have "resulttype" (but Geoserver
tries anyway). It's in both 1.1.0 and 2.0.0 though.
So looks like a bug, reported as http://jira.codehaus.org/browse/GEOS-6145
=====
One thought - shouldn't resulttype=hits return the *actual* number of
features that satisfy the user-query, not the number that satisfy the query
after GeoServer has added the maxfeatures to it?
So if the limit is 7500, and my database contains 10,000,000, shouldn't it
return 10,000,000?
The specs don't say clearly one way of the other which it should be.
Cheers,
Jonathan
