SwishResult->stem

(no version information, might be only in CVS)

SwishResult->stem -- Stems the given word

Description

array SwishResult->stem ( string word )

Warning

This function is EXPERIMENTAL. The behaviour of this function, the name of this function, and anything else documented about this function may change without notice in a future release of PHP. Use this function at your own risk.

Stems the word based on the fuzzy mode used during indexing. Each result object is linked with its index, so the results are based on this index.

Parameters

word

The word to stem.

Return Values

Returns array containing the stemmed word variants (usually just one).

Errors/Exceptions

Throws SwishException on error.

Examples

Example 1. Basic () 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 th 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"
}
