php - MYSQL全文索引存在但显示错误1191

Question

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

此查询在实际服务器上运行良好，但在本地服务器上失败。我认为表可能有问题，因此将所有实际服务器表导入到本地服务器但仍然无法正常工作。

我非常确定所有索引都存在并且所有表都在使用 MyISAM 引擎。

索引列表:

1) e_pj_keywords uk 表中的 uk.Keyword_Name

2) post_jobs 表中的 a.company_name & a.company_type

3) 位置j表中的j.location_name

我已经引用了stackoverflow & google的所有问题来解决这个错误但是不能。

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。请帮忙。

下面是我的查询

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进行查询 - 如果您正在执行多字段 match，则必须有一个在同一索引中包含这两个字段的 SINGLE 全文索引。

您必须为每个索引拆分匹配项，或者创建一个包含这两个字段的新索引，例如

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

或

FULLTEXT KEY `foo` (company_name, designation)
