Hello,
This snippet may help to understand TopDocs:

Also, paging through Lucene results is 'do-it-yourself' exercise using
hits.length() until someone contributes a good implementation.
Oversimplifying, if you want 10 hits per page:
hitsperpage equals ten;
-if hits length is less than ten, you have one page
-else if hits length/hitsperpage modulos is 0, that's your pagecount
-else hits length/hitsperpage is your pagecount, modulos is for your
last page
You will also need a variable to keep track of which page you are on
and a static
method which returns min/max values to be included in your iteration
loop.
You can also see my previous attempt at solving this:

I might be missing something because TopDocs seems to only be about
finding the relevancy of documents and HitCollector doesn't seem to be
relavent either.

See TopDocs, HitCollector, etc. Don't iterate through a Hits
objects to
get docs beyond, say, 100 since it's designed to efficiently return
the
first 100 documents but re-executes the queries each 100 or so
times you
advance to the next document.

Hello,
I was wondering if Lucene provides any mechanism which helps in
pagination. In other words is there a way to return the first 10 of
500 results and then the next 10 and so on.
