[Xapian-discuss] Get Document Position in Search

[Ryan Bates]

Yeah, it's tricky to keep this kind of session state across requests to a
web app so I was hoping to avoid that. I also do expect the database to
change during the session which adds an extra layer of complexity to that
approach.
Still hoping there is some way to do this on a per-request basis since it
would greatly simplify things.

Thanks though,

Ryan
