ORDER BY something？ – jarlh

这是什么东西，它不能满足它应该像排名或东西，但如何做到这一点 – The6thSense

使用FREETEXTTABLE而不是FREETEXT。这会给你一个结果集比赛，包括Rank，你可以订购by.Refer this为更多的有识之士

SELECT TOP 3 RANK, [KEY] 
FROM FREETEXTTABLE(TABLE_NAME,content,'health care') 
ORDER BY RANK DESC

加入由KEY从原来的表中获取列。

SELECT TOP 3 TABLE_NAME.* 
FROM FREETEXTTABLE(TABLE_NAME,content,'health care') as fullTextResults 
join TABLE_NAME on fullTextResults.[KEY] = TABLE_NAME.Id 
ORDER BY fullTextResults.RANK DESC
