<?php try {
$swish = new Swish("index.swish-e"); $search = $swish->prepare();
$results = $search->execute("time"); echo "First query found: ", $results->hits, " hits\n";
$i = 0; while($result = $results->nextResult()) { echo "Hit #", ++$i, " - ", $result->swishdocsize, " bytes\n"; }
$search->setLimit("swishdocsize", "3000", "6000"); //limit by document size, from 3000 to 6000 bytes $results = $search->execute("time"); echo "Second query found: ", $results->hits, " hits\n";
$i = 0; while($result = $results->nextResult()) { echo "Hit #", ++$i, " - ", $result->swishdocsize, " bytes\n"; }
} catch (SwishException $e) { echo $e->getMessage(), "\n"; }
?>
