[Xapian-discuss] PHP Estimated results query bug

[Ross Lawley]

Hi

I'm using Xapian with PHP and when getting a matchset I'm checking for
at least a 100 hits, so to improve the estimated number of results.

That works fine but when I do a sort by value then it doesn't return
the same figure:

{{{
 $xapian_enquire->set_query($xapian_query);
 if($sortby == 'date'){
  $xapian_enquire->set_sort_by_value(0, true);
 }
 $xapian_matchset = $xapian_enquire->get_mset($page*$count, $count, 100);
 $results->setParameter('size', $xapian_matchset->get_matches_estimated());
}}}

I have cases where the matchset size is 15 but if do the same search
and I sort by date the initial estimated size returns 14

This is using  xapian-core 1.0.2
