I've specified the fields in schema.xml as such: <field name="id" type="binary" indexed="true" stored="true" required="true" multiValued="false" /> I'm able to add records to the index via a POST request, encoding and sending the fields as Base64 Strings.

I cannot find any good turtorial with simple, easy to

问题 as specified here cursormark is stateless but I don't get how it it is solving deep paging issue if its stateless. Does solr stores the indexed data in sort by unique key field if so then it will clarify my confusion. if I am wrong please explain how the cursormark solves deep paging.
