说明

array SwishResult::stem ( string $word )
Warning

此函数是实验性的。此函数的表象,包括名称及其相关文档都可能在未来的 PHP 发布版本中未通知就被修改。使用本函数风险自担 。

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.

参数

word

The word to stem.

返回值

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

错误/异常

Throws SwishException on error.

范例

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";
}

?>

以上例程的输出类似于:

array(1) {
  [0]=>
  string(4) "test"
}
array(1) {
  [0]=>
  string(5) "other"
}
