[Exist-open] Cursor like functionality

[Hank R. <ha...@cr...>]

Hello,

I make some queries that simply cannot be optimized
because they compare so many elements.  In a sql 
database, I would make the query once and use a cursor
to page through the result.

The REST interface conveniently returns the @hits, 
@start and @count. Perhaps I am doing something else 
wrongly, but calling the same query again, with a 
new _start still appears to process the whole long 
query again.

Has there been some discussion of a result that 
persists for the session, so that the same query with 
and new _start works like a cursor?

Thank you,
Hank
