思維獅身人面像 - 按年份和相關性排序

Question

我在使用ThinkingSphinx作爲網頁上的搜索引擎。我需要的是按年份和相關性對搜索結果進行排序。

由於order: "DATE_FORMAT(created_at, '%Y') DESC"不起作用，時間段根本無用，因爲我想要什麼，我正在擺脫想法。

Answer 1

YEAR函數可以滿足您的需求，但值得注意的是您需要在SELECT子句中使用它，給結果一個別名，然後在您的ORDER子句中引用該別名。

這是假設你正在使用TS V3：

Model.search 'foo', 
    :select => '*, YEAR(created_at) as created_at_year, weight() as weight', 
    :order => 'created_at_year DESC, weight DESC'
