Yeah, multiple tabs/windows is one reason I avoid too much session state. I
could normally store the offset in the URL but see below on why that won't
work.

In this situation the items are being edited at the same time (think of an
"edit next" button on a form). This spawns a background process which
updates the Xapian database within minutes, so the chances are quite high
the modifications will change the search results. Storing a simple offset
won't work here since it could easily skip records.
