div.yiv1170366800WordSection1 {}#yiv1170366800 Hi, Geoserver implements WFS
standards so all parameters can be found from the documents on
pagehttp://www.opengeospatial.org/standards/wfs Parameters are somewhat
different in different WFS versions. That paging does not work in a reliable
way without sorting does not come from the standards, it is just a Geoserver
peculiarity. A not complete but faster to read list is
inhttp://docs.geoserver.org/stable/en/user/services/wfs/reference.html
Geoserver supports also a simplified method for making queries
http://docs.geoserver.org/stable/en/user/tutorials/cql/cql_tutorial.html As far
as I know no other WFS server supports CQL queries. -Jukka Rahkonen-

Aihe: [Geoserver-users] Σχετ: WFS query with limit and offset Thank you very
much for this clarification. Is there a document/tutorial where I can find
all the parameters that can be used in a GeoServer URI when querying the data?

you will get the features in FID order which may or may not be fixed depending
on the backend. I would always set the sort attribute when paging. Ian On

Hello Ian, Thank you very much for your fast response. I read the blog
post that you mentioned and it helped greatly, but I still have one question.
What I have not understood is if the sorting is mandatory, to ensure the
smooth retrieval of the information, or not. I feel that the post implies that
it is not mandatory, and some testing that I did seems to confirm that, but I
would like to know for sure. I think that if not specified, the sorting is done
by the back end on the first propertyName? Thank you once more for your time
and the helpful information. Best regards, Maria. Στις 3:52 μ.μ.

blog post
(https://www.geo-solutions.it/blog/wfs-for-the-masses-adding-support-for-paging-and-sorting-in-geoserver/)
seems to cover this. So it looks like since 2.1 GeoServer has allowed you to
make queries like:
http://localhost:8080/geoserver/topp/ows?service=WFS&version=1.0.0&request=GetFeature
&typeName=topp:states&outputFormat=csv&propertyName=STATE_NAME,PERSONS
&maxFeatures=10&startIndex=10&sortBy=PERSONS%20D I think the syntax changed
for WFS 2.0 but I can't find a reference just now Ian On Mon, 20 Aug 2018

Hello everyone, I have set up a GeoMesa Accumulo datastore and I would like
to fetch the data using a limit and an offset (with some sorting if it is
required) but I have not managed to find if this is possible or not. I have
found only this
http://osgeo-org.1560.x6.nabble.com/Specifying-an-offset-in-a-WFS-GetFeature-request-td3802601.html
but it is from 2009 and I cannot find any follow-up. Can you please let me
know if this is possible or not? Or if there is any tutorial/documentation
about what can be used as filter in a WFS GetFeature request? Thank you very
much for you time. Best regards, Maria.
