Magento：改進搜索引擎（變形，無關詞語移除等）

Question

我很想知道我是否可以檢測變形（如狗/狗），刪除不重要的單詞（「在美國製造」 - > 「in」和「the」不重要）等等，而不用在一個大的PHP代碼塊中硬編碼這樣的許多場景，用戶爲Magento搜索引擎輸入的搜索字符串。我可以在一定程度上處理這個搜索字符串，但它看起來不衛生和醜陋。

任何建議或使其成爲「intelliegent」搜索引擎的指針？

使用這個類：

class Inflection 
{ 
    static $plural = array(
    '/(quiz)$/i' => "$1zes", 
    '/^(ox)$/i' => "$1en", 
    '/([m|l])ouse$/i' => "$1ice", 
    '/(matr|vert|ind)ix|ex$/i' => "$1ices", 
    '/(x|ch|ss|sh)$/i' => "$1es", 
    '/([^aeiouy]|qu)y$/i' => "$1ies", 
    '/(hive)$/i' => "$1s", 
    '/(?:([^f])fe|([lr])f)$/i' => "$1$2ves", 
    '/(shea|lea|loa|thie)f$/i' => "$1ves", 
    '/sis$/i' => "ses",

如果你有時間使用拐點使用一種標準的方式：http://en.wikipedia.org/wiki/Inflection

可以作爲陣列使用XML結合，從而把所有的拐點數據，看看如何codeigniter的變形非常友好：http://ellislab.com/codeigniter/user-guide/helpers/inflector_helper.html

許多框架都支持內置拐點，但它只會專注於主要英語。對於其他語言，您應該自己編寫...或者如果您需要，可以使用unicode.org以及其他語言的某些轉換標準。
