sphinx 全文搜索引擎：顧名思義，是做收索用的，因為普通的搜索在數據量小的時候，能應對自如，但是當數據量上千萬，或者上億的時候。純粹的sql搜索顯得緩慢，無力。因而為了提高用戶體驗，增快用戶的搜索速度，出現了sphinx 。簡單的例子比如大型網站的首頁搜索。

Coreseek發布了3.2.14版本和4.1版本等多個版本
3.2.14版本是2010年發布的，它是基于Sphinx0.9.9搜索引擎的。4.1版本是2011年發布的
，它是基于Sphinx2.0.2以后的

    1.檢查中文環境語言
    2.升級依賴包
    3.下載并安裝mmseg（coreseek所需要的詞典）
    4.安裝coreseek的csf-3.2-14（也就是sphinx）
    5.安裝配置sphinx并運行生成相應的索引
    6.啟動sphinx，php文件調用sphinx服務即可
    7.配置php支持sphinx （或者引用sphinx類直接調用sphinx也行）
    
注意事項：①、采用API調用，如使用PHP、java等的API函數或方法查詢。優點是可不必對mysql重新編譯，服務端進程“低耦合”，且程序可靈活、方便的調用；需要二次查詢。
二次查詢注：到現在發布版本為止——sphinx-0.9.9，sphinx在檢索到結果后只能返回記錄的ID，而非要查的sql數據，故需要重新根據這些ID再次從數據庫中查詢，
