Question

我有一个以 id，主题，描述，图片网址作为列的表格。像

这样的条目

id   topic               description    image_url
1    People and blogs    TownHall       http://...
2    People and blogs 2  ......         .......
3    Blogs               .......        .......
4    Good                ......         ......

当我将博客搜索为查询输入时

SELECT * FROM people 
WHERE MATCH(topic,descript) AGAINST ("blogs" WITH QUERY EXPANSION)

我的结果是

1  People and blogs    TownHall    http://.../
2  People and blogs 2  ......      ......./
3  Blogs               .......     ......./

第三行应该是第一行，因为它是确切的词（博客），其余的行应该在此之后...

请帮我调试一下。

Answer 1

尝试类似：

{{link-to}}

Answer 2

尝试以下SQL，它将解决您的问题。

SELECT people.*
  FROM people
order by MATCH(topic,descript) AGAINST ("blogs" WITH QUERY EXPANSION) asc;

输出：

+------+--------------------+-------------+
| id   | topic              | descript    |
+------+--------------------+-------------+
|    3 | Blogs              | ........    |
|    2 | People and blogs 2 | ........    |
|    1 | People and blogs   | TownHall    |
+------+--------------------+-------------+
