mysql - 使用 MATCH AGAINST 查询字符串返回的不仅仅是严格相等的字符串

Question

我正在尝试选择MATCH AGAINST在 MySQL 中使用的产品。

标题的长度指定为单个数字加上m米的字母，即1m,2m等5m。

当我尝试5m network cable与下面的查询匹配时，它也会返回0.5m network cable等1.5m network cable。

如何MATCH在 2 个字符的字符串上获得准确的单词？

我的查询：

SELECT title, category, price
FROM products_table
USE index (prod_idx)
WHERE (MATCH (title) AGAINST ('+"5m" +"network" +"cable"' IN BOOLEAN MODE))

Answer 1

The problem is that FULLTEXT think of '.' as a word ender/starter/separator, but you want to think of it as a letter. So, turn it into a letter:

When inserting data, change '.' to '_' so that 0.5m becomes 0_5m, which will treated as a word. Do the same change in the search string.
