SQL Server 2016，如何在数据库的多个单词搜索中使用CONTAINS（）？

Question

New to SQL for the most part so perhaps there is a better approach but I'm looking for a way to search through a database using a textbox which can take any number of words/numbers. Basically like a search engine. Columns to be searched: [Col1], [Col2], and [Col3]

I have the table Full-Text indexed, is there a way I can use CONTAINS for this?

DECLARE @Search nvarchar(500)
SET @Search = 'foo 7 bar' -- can have multiple words/numbers

SELECT *
FROM TableName
WHERE CONTAINS([Col1] or [Col2] or [Col3], @Search)

I realize the last line syntax is incorrect but that's basically what I'm looking for. Shouldn't be exact match or case sensitive, nor should the order of wording matter ('red cat' = 'cat red') . Also would like to show results for close matches, ie, some of the keywords don't match anything.

Thank you!

Answer 1

Your each search word must be surrounded in quotes..

'"Hi" AND "I" AND "am" AND "Yogeesha"'

事实证明，使用FREETEXT()得出我一直在寻找的结果。
