<?php
#java_set_library_path("/usr/lib/jre/lib/ext/lucene-
1.4.3.jar:/usr/lib/jre/lib/ext/my.jar");
function microtime_float()
{
list($usec, $sec) = explode(" ", microtime());
return ((float)$usec + (float)$sec);
}
$location="/var/www/html/test/index";
//$location = "/var/www/index/emp";

$time_start = microtime();
$hits = new java("org.apache.lucene.search.Hits");

//echo $indexreader;
$reader_ref = $indexreader->open($location);
$searcher = new java

$queryparser = new java("org.apache.lucene.queryParser.QueryParser");

$sort = new java("org.apache.lucene.search.Sort",$sortfield);
$system = new Java('java.lang.System');
$startTime = $system->currentTimeMillis();
$hits = $searcher->search($query,$sort);
$endTime = $system->currentTimeMillis();
//$time_end = microtime(true);
$start = 0;
$max = 50;
echo "hits".$hits->length();
echo "<br>";
if ($hits->length()!=0 ) {
if (@$_GET['startat'] && @$_GET['maxresults']) {
$start = $_GET['startat'];
$max = $_GET['maxresults'];
}
$thispage = $max;
if ($start+$max > $hits->length()) {
$thispage = $hits->length()-$start;
}

}
}

$search_time = round($search_time,3);
echo 'search response:'.$search_time.'secs<br>';
echo 'number of hits:'.$hits->length();
?>
<form>
<table>
