跨多个表的MySQL全文搜索 [英] MySQL full text search across multiple tables

问题描述

我有一系列包含要全文搜索的数据的表。我已经试过将表与 UNION 结合，但是结果会丢失其全文索引，因此无法进行全文搜索。我不认为将数据放入临时表是一种方法。有没有办法可以全文检索这些表格？

更新：
我的全文查询是

  SELECT ID，标题，描述，作者，MATCH（标题，标签，正文）反对（搜索条款）AS相关性
 FROM [表格组合（b）b 
 WHERE MATCH（标题，标签，正文） >解决方案

MySQL无法在多个表中创建全文（或任何）索引。因此，使用单一索引是不可能的。

或者，您可以：

1. 在每个表上使用索引，并根据需要使用联合/联合来检索符合要求的行。 创建一个聚合表来应用索引。

使用诸如lucene或solr之类的工具来提供搜索索引。


2. （如果您打算进行任何比例缩放，这可能是最佳选择）

I have a series of tables that contain data I want to full text search. I've tried combining the tables with UNION, but the result loses its fulltext index so can't be fulltext searched. I don't think that putting the data into a temp table is the way to go. Is there someway that I can fulltext search these tables efficiently? Thanks in advance!

UPDATE: my query for fulltext was

SELECT ID, Title, Description, Author, MATCH (Title,Tags,Body) AGAINST ("search terms") AS Relevance 
FROM [combination of tables goes here] 
WHERE MATCH (Title,Tags,Body) AGAINST ("search terms")

解决方案

MySQL can't make a fulltext (or any) index accross multiple tables. So using a single index is out.

As an alternative, you could either:

1. Use an index on each table, and a join/union as appropriate to retrieve the rows that match your requirements.

2. Create an aggregate table to apply the index to.

3. Use a tool such as lucene or solr to provide your search index. (If you are going for any sort of scale, this is likely the best option)
