lucene

I'm using lucene on a site of mine and I want to show the total result count from a query, for example:

Showing results x to y of z

But I can't find any method which will return me the total number of potential results. I can only seem to find methods which you have to specify the number of results you want, and since I only want 10 per page it seems logical to pass in 10 as the number of results.

Or am I doing this wrong, should I be passing in say 1000 and then just taking the 10 in the range that I require?
