Question

我在早期版本的Wamp Server（2.5）中成功使用了以下查询，直到升级到3.0版。

此查询在实际服务器上正常工作，但在本地服务器上失败。我认为表可能有问题，因此将所有实际的服务器表导入到本地服务器但仍无效。

我非常确定所有索引都存在＆amp;所有表都使用MyISAM引擎。

索引列表：

1）uk.Keyword_Name in e_pj_keywords uk table

2）a.company_name＆amp; post_jobs中的a.company_type表

3）位置j表中的j.location_name

我已经使用过stackoverflow＆amp;的所有问题的参考资料。谷歌解决这个错误，但不能。

还为所有相关表启用了KEYS，但没有任何效果。

Can't find FULLTEXT index matching the column list

我知道会有非常小的错误但无法捕捉到它。请帮助。

以下是我的查询

鉴于这些表格描述，这是您的问题：

OR MATCH (company_name, Designation) AGAINST 
            ^^^^^^^^^^^^^^^^^^^^

您没有包含这两个字段的任何单个FULLTEXT索引。 MySQL不会将两个单独的全文索引组合在一起用于查询 - 如果您正在进行多字段match，那么必须有一个单一的全文索引，其中包含同一索引中的这两个字段。

您必须为每个索引拆分匹配项，或创建包含两个字段的新索引，例如

... MATCH 'foo' AGAINST (company_name) OR MATCH 'foo' AGAINST (desgination)

或

FULLTEXT KEY `foo` (company_name, designation)

存在MYSQL全文索引，但显示错误1191
