Question

我有2个主要表格（professional_account＆amp; professional_profile）和3个子表格（prof_knows_about，prof_keywords＆amp; prof_recent_jobs） 1：很多关于professional_profile 。

FT搜索应匹配professional_profile.professional_statement中的搜索词，或者prof_knows_about.knowledge_desc的任何行（针对该professional_id），或者prof_keywords.keyword的任何行或prof_recent_jobs.job_title的任何行

在5.6.35服务器中，它按预期工作，但在5.7.10中，如果搜索项位于professional_profile.professional_statement或prof_knows_about.knowledge_desc中，我只会得到结果 - 在其他两个表中找不到搜索词。两个服务器都在freeBSD UNIX上运行。

我尝试将两个服务器粘贴到shell中。两者也提供相同的EXPLAIN输出。使用5.6上5.7的转储来确保相同的数据和表创建。

我在两台服务器上都显示了变量，但很难比较，因为5.7中有很多额外的值。将两者都设置为相同的sql_mode。

下面列出的表格，查询和解释。

这是我的查询或我的5.7服务器的问题吗？

使用MySQL 5.6而不是5.7
