Hi, In my current implementation of Lucene 4.3 where there are millions of indexed records, I do a regular search() and get the topDocs.totalHits as the count of results.
As part of this, I store all the results in the session and then let the user paginate through the results. With this, I am able to show the "First" "Previous" "Next" and "Last" links for navigation along with the "Page 1 of 500" display. Obviously, this led to memory issues and I have now decided to use the searchAfter() method and hence avoid storing the huge result set in memory. Question 1: How can I get the total result count in this case? Is it even possible as I won't be getting the entire resultset? Question 2: I know I can provide the "Previous" and "Next" options for paginating, but is there anyway I can still provide the "Last" page option, as to do that I would need to provide the document object just before the last page begins. Please suggest.
