Example #1 Basic SwishSearch::setLimit example


<?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";
}

?>

The above example will output something similar to:

First query found: 5 hits
Hit #1 - 4261 bytes
Hit #2 - 37937 bytes
Hit #3 - 7126 bytes
Hit #4 - 15427 bytes
Hit #5 - 4768 bytes
Second query found: 2 hits
Hit #1 - 4261 bytes
Hit #2 - 4768 bytes
