mysql - 全文搜索不适用于多列

Question

SELECT `id`, `name`, `frontCover`, `type`, `category`, `user`, `author`, `MRP`, `sellingPrice`, `isNew`, `isRaw`, `binding`, `publisherName`, `publicationYear`, (MATCH name,author AGAINST ("made easy editorial board" IN BOOLEAN MODE)) AS relevance FROM `books` WHERE LOWER(type) = 'college' AND (MATCH name,author AGAINST ('made easy editorial board' IN BOOLEAN MODE)) AND `status` = 1 ORDER BY `relevance` DESC

尝试运行查询时出现错误

#1191 - Can't find FULLTEXT index matching the column list

我已添加姓名和作者全文索引。但是当我运行单列时它可以工作。我需要从两列匹配结果中获取。

Answer 1

当您在查询中使用这两列时，您需要在这两列上建立组合的 FULLTEXT 索引。

ALTER TABLE `books` 
ADD FULLTEXT INDEX `IDX_FULLTEXT_NAME_AUTHOR` (`name` ASC, `author` ASC);
