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" }
