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" ;
}
