如何在mysql中使用JOIN搜索改进我的LIKE?

时间:2021-10-09 05:54:56

I currently have a search that looks like this:

我目前的搜索结果如下:

SELECT s.ID 
    FROM Shoe s
        INNER JOIN Account a
            ON s.UserID = a.ID
        WHERE s.Publish='1' AND
            (s.Brand LIKE '%$Search%'
             OR s.Name LIKE '%$Search%'
             OR s.PrimaryColor LIKE '%$Search%'
             OR a.User LIKE '%$Search%') 
        ORDER BY s.ID DESC
LIMIT $offset, $rowsPerPage"

This works fine when I do a search such as "Blue" or "Nikes", but if I do a search such as "Blue Nikes" nothing returns. Should I use FULLTEXT? How can I improve this? I want to be able to search all columns that may relate to the search variable.

当我进行诸如“蓝色”或“耐克”之类的搜索时,这样可以正常工作,但如果我进行诸如“蓝色耐克”之类的搜索,则无法返回。我应该使用FULLTEXT吗?我怎样才能改善这个?我希望能够搜索可能与搜索变量相关的所有列。

So after messing around and testing different things, I came up with this:

所以在搞乱并测试不同的东西之后,我想出了这个:

"FROM Shoe AS s
    LEFT JOIN Accounts AS a ON s.UserID = a.ID
    WHERE (MATCH (s.Brand, s.Name, s.PrimaryColor AGAINST('$Search' IN BOOLEAN MODE)
        OR MATCH (a.User) AGAINST('$Search' IN BOOLEAN MODE))
            AND s.Publish='1'
    ORDER BY s.ID DESC"

This seems to fix my issue that I mentioned above, I can now do a search such as "Blue Nike" and all items related to blue & nike will show up. Not sure if this is the most efficient way to go about it, but it does work.

这似乎解决了我上面提到的问题,我现在可以进行搜索,例如“Blue Nike”,所有与blue&nike相关的项目都会显示出来。不确定这是否是最有效的方法,但确实有效。

Instead of LIKE try using SOUNDEX, or both.

而不是LIKE尝试使用SOUNDEX,或两者兼而有之。

Secondly, you may want to optimize the query to maintain capitalization, for example:

其次,您可能希望优化查询以维护大小写,例如:

(lower(s.Brand) LIKE '%" . strtolower($Search) . "%'
OR lower(s.Name) LIKE '%" . strtolower($Search) . "%'
OR lower(s.PrimaryColor) LIKE '%" . strtolower($Search) . "%'
OR lower(a.User) LIKE '%" . strtolower($Search) . "%')
