首先，您需要在生产服务器上启用“全文本搜索”索引，因此，如果这不在范围之内，那么您就不希望这样做。
但是，如果已经准备好了，则全文搜索相对简单。
FREETEXT是最简单的，可以这样完成：
SELECT UserName
FROM Tbl_Users
WHERE FREETEXT (UserName, 'bob' )
Results:
JimBob
Little Bobby Tables
FREETEXTTABLE的功能与FreeTEXT相同，不同之处在于它以表形式返回结果。
T-sql全文搜索的真正功能来自CONTAINS（和CONTAINSTABLE）谓词…这是一个很大的谓词，因此我将其用法粘贴到：
CONTAINS
( { column | * } , '< contains_search_condition >'
)
< contains_search_condition > ::=
{ < simple_term >
| < prefix_term >
| < generation_term >
| < proximity_term >
| < weighted_term >
}
| { ( < contains_search_condition > )
{ AND | AND NOT | OR } < contains_search_condition > [ ...n ]
}
< simple_term > ::=
word | " phrase "
< prefix term > ::=
{ "word * " | "phrase * " }
< generation_term > ::=
FORMSOF ( INFLECTIONAL , < simple_term > [ ,...n ] )
< proximity_term > ::=
{ < simple_term > | < prefix_term > }
{ { NEAR | ~ } { < simple_term > | < prefix_term > } } [ ...n ]
< weighted_term > ::=
ISABOUT
( { {
< simple_term >
| < prefix_term >
| < generation_term >
| < proximity_term >
}
[ WEIGHT ( weight_value ) ]
} [ ,...n ]
)
这意味着您可以编写查询，例如：
SELECT UserName
FROM Tbl_Users
WHERE CONTAINS(UserName, '"little*" NEAR tables')
Results:
Little Bobby Tables
