p.s. To avoid that issue you could store the result-sets document ids in
the session.

Yes, I was thinking about index updates.
Getting a different result set when you go back to a
previous page might be an issue - could always cache
each page as its opened rather than the entire result
set.

Hi Marc,
I'm using this method for a web-application. I'm
storing only the
current viewable set of documents in the session and
re-query if the user
scrolls to the next page. This method is pretty fast
and has a minimal
session- and processing-footprint. But, if your
index is changed during
scrolling and that affects the query and you're
re-querying, you will
maybe get confused about new docs :-)

I read somewhere recently (maybe even on this

recommendation to requery each time for successive
pages as this avoids some of the complexity
involved
in session management. Whats peoples view of this?

Our application presents search results in a
paginated form.
We were unable to find Searcher methods that
would
return, say, 'n'
(typically, 10) hits after a start offset 'k'.
So we're currently using the Hits collection
returned by
Searcher.search,
and using its Hits.doc(i) method to get the ith
hit, with i between
k and
k+n. Is that the most efficient way to do that?
Is
there a better
way (e.g.
some form of Filter on the query itself)?
You probably want to do it just the way you do.
But cache the Hits somehow. Perhaps in a session,
perhaps globally
in /your/ searcher. Perhaps the session points
at
the global cache
so it doesn't change within a session when you
flush
the cache on
index update.
