多表全文搜索對兩個PHP變量

Question

我有三個信息表business_id是公共線程。我有兩個輸入字段，一個用於常規搜索（用戶可以搜索他們想要的任何內容）和一個zip輸入。在PHP方面，我找到了一般搜索字符串，並將其設置爲$search，並將zip設置爲$zip。

我如何使用$search變量MATCH任何全文indecies 然後限制使用從表C $zip然後僅返回ID那些比賽嗎？

我的數據庫結構如下：

table coup 
    id << this is the my desired information from the search 
    timestamp 
    business_id 
    coupvalue 
    startdate 
    enddate 
    username 
    status 
    terms 
    image 
    description 
     primary = id 
     fulltext = name 
table bloc 
    id 
    address 
    city 
    state 
    zip 
    business_id 
    phone 
    lat 
    lon 
     primary = id 
table bus 
    business_id 
    name 
    timestamp 
    category 
    subcat 
     primary = business_id 
     fulltext = name,category,subcat 

任何幫助，將不勝感激！

Answer 1

您可以使用or狀態與比賽：

select 
    c.id 
from 
    coup c 
    inner join bus b on 
     c.business_id = b.business_id 
    inner join block z on 
     c.buisness_id = z.business_id 
    where 
     (match(c.name) against ('$search') 
     or match (b.name, b.category, b.subcat) against ('$search')) 
     and z.zip = '$zip' 

我沒有基準，但是，這個可能會更快：

select 
    c.id 
from 
    (select id, business_id 
    from coup 
    where match(name) against ('$search') 
    ) as c 
    left join 
     (select business_id 
     from bus 
     where match(name, category, subcat) against ('$search') 
     ) as b on 
     c.business_id = b.business_id 
    inner join bloc z on 
     c.business_id = z.business_id 
where 
    z.zip = '$zip'
