Hi,
Then the last thing to do would be to make Simone to edit the previously
mentioned blog
http://www.geo-solutions.it/blog/wfs-for-the-masses-adding-support-for-paging-and-sorting-in-geoserver/.
The blog is quite high on search results of “geoserver+startindex” and but the
examples do not work in the same way with current Geoserver versions. Text
should emphasize that for reading the first page of features user must
explicitly use “startindex=0”. Editing the text would be better than to add a
comment because all users do not read the comments.
Geoserver documentation mentions that startindex exists in
http://docs.geoserver.org/stable/en/user/services/wfs/basics.html. However,
there is nothing about it in WFS reference
http://docs.geoserver.org/stable/en/user/services/wfs/reference.html.
Startindex is included in the WMS manual
http://docs.geoserver.org/stable/en/user/services/wms/vendor.html but text is
not totally up to date. Startindex works nowadays with all stores and it would
be worth telling also here that startindex=0 may give different results than
request that does not have startindex at all.

Hi,
OK, with the startindex values I did not see that startindex is changing the
sorting to alphabetical. Plain GetFeature with maxFeatures returns features in
order states.1, states.2, states.3 but adding startindex is really changing the
order into states.1, states.10, states.11.
I perhaps agree that current behaviour is acceptable bu it is not logical, and
Geoserver users must know that they must load data in pages always with
startindex because startindex=0 does not return the sama data than if parameter
is not used at all.
It may be counter-intuitive, I agree, but forcing a sort is the only way to get
stable paging across all data sources.
But of course, we initiate that only if the client shows an intent to page,
without a startIndex we avoid it to get better performance.
Cheers
Andrea
