Examples
Example #1 Basic SwishResult->stem() example
<?php
try {
$swish = new Swish("ext/swish/tests/index.swish-e");
$results = $swish->query("testing OR others");
if ($result = $results->nextResult()) {
var_dump($result->stem("testing")); //the results fully depend on the stemmer used in the index
var_dump($result->stem("others"));
}
} catch (SwishException $e) {
echo "Error: ", $e->getMessage(), "\n";
}
?>
The above example will output something similar to:
array(1) {
[0]=>
string(4) "test"
}
array(1) {
[0]=>
string(5) "other"
}
