The swish extension provides the bindings for Swish-e API. Swish-e stands for "Simple Web Indexing System for Humans - Enhanced" and is an open source system for indexing and search. Swish-e itself is licensed under GPL license, but uses a clause that allows applications to link against the library if every copy of the combined work is accompanied by the URL to Swish-e source code. Here it is: » http://swish-e.org.
Esta extensión es EXPERIMENTAL. Esto significa que el comportamiento de esta extensión, los nombre de sus funciones y en definitiva TODO lo documentado sobre esta extensión, puede cambiar en una futura versión de PHP SIN AVISO. La advertencia queda hecha, y utilizar esta extensión queda bajo su propia responsabilidad.
PECL/swish requires PHP 5.1.3 or newer.

Esta extensión no tiene directivas de configuración en php.ini.
Example#1 Basic search query
<?php
try {
$swish = new Swish("index.swish-e");
$results = $swish->query("test OR text");
echo "Found ", $results->hits, " results\n";
while ($result = $results->nextResult()) {
var_dump($result);
break; //break after the first result
}
} catch (SwishException $e) {
echo "Error: ", $e->getMessage(), "\n";
}
?>
El resultado del ejemplo seria algo similar a:
Found 9 results object(SwishResult)#3 (8) { ["swishreccount"]=> int(1) ["swishrank"]=> int(1000) ["swishfilenum"]=> int(10) ["swishdbfile"]=> string(13) "index.swish-e" ["swishdocpath"]=> string(23) "README.SUBMITTING_PATCH" ["swishtitle"]=> NULL ["swishdocsize"]=> int(4557) ["swishlastmodified"]=> int(1072136752) }
Estas constantes están definidas por esta extensión y estarán disponibles solamente cuando la extensión ha sido o bien compilada dentro de PHP o grabada dinámicamente en tiempo de ejecución.
