Question

我是php开发人员，我的MySQL全文搜索有问题。

这是我的查询

select distinct j.jobid,headline,company,country,state,city,location,
date_format(str_to_date(posted_dt, '%m-%d-%Y %H:%i:%s' ), '%M %d, %Y') posted_dt,joblinks 
from jobs j 
left join job_filters jf on jf.jobid = j.jobid 
left join job_emptype_map em on j.jobid = em.jobid 
left join job_sub_emptype_map sem on em.jobid = sem.jobid and em.emp_type = sem.emp_type 
where status=1 
And MATCH (headline,description,pri_skills,company) AGAINST ('java developer' IN natural language MODE) > 1 
And MATCH (location,country,state,city,zipcode,other_loc) AGAINST ('california, United States' WITH QUERY EXPANSION ) > 1 
order by str_to_date(posted_dt,'%m-%d-%Y %H:%i:%s') DESC limit 0,25

我通过上述查询获得了正确的结果。但它正在采取（显示行0 - 24（总共25个，查询花了50.6951秒。）

当我更改关键字＆＃34; ui developer＆＃34;而不是＆＃34; java开发人员＆＃34;然后我得到0结果

如果我检查关键字＆＃34; ui developer＆＃34;有了相似的功能，我就会得到结果。

我不明白为什么匹配功能仅适用于某些关键字，以及为什么我的托管计划是云时需要花费太多时间。

我现在正在使用云服务器计划，我已使用类似功能更新了我的查询，现在我的查询是......

select distinct j.jobid,headline,company,country,state,city,location,date_format(str_to_date(posted_dt, '%m-%d-%Y %H:%i:%s' ), '%M %d, %Y') posted_dt,joblinks, (select count(distinct j.jobid) as jobcount from jobs j left join job_filters jf on jf.jobid = j.jobid left join job_emptype_map em on j.jobid = em.jobid left join job_sub_emptype_map sem on em.jobid = sem.jobid and em.emp_type = sem.emp_type where status = 1 and (concat(headline,' ',description,' ',pri_skills,' ',company) like '%java programer%' ) And ( country like '%United States%' ) ) jobcount from jobs j left join job_filters jf on jf.jobid = j.jobid left join job_emptype_map em on j.jobid = em.jobid left join job_sub_emptype_map sem on em.jobid = sem.jobid and em.emp_type = sem.emp_type where status=1 and (concat(headline,' ',description,' ',pri_skills,' ',company) like '%java programer%' )And ( country like '%United States%' ) order by str_to_date(posted_dt,'%m-%d-%Y %H:%i:%s') DESC limit 0,25

我在上面的查询之间写了选择查询的分页，上面的查询得到了很好的结果，但是花了太多时间，请注意：我的工作表有大约50,000多条记录

PHP MySQL Match（）反对（）全文搜索不适用于某些关键字
