仅查找与FULLTEXT索引的完全匹配

Question

我有一个短语表：

buy car
adopt cute cat
make big money
buy helicopter
big nasty dog

带有FULLTEXT索引。我想找到在给定文本中完全出现的所有短语。

对于文字：

I want to buy car and then buy and adopt cute cat tomorrow.

我应该得到：

buy car
adopt cute cat

我尝试过查询：

SELECT * FROM `phrases` WHERE MATCH(`phrase`) AGAINST('I want to buy car and then buy and adopt cute cat tomorrow.' IN BOOLEAN MODE)=`numWords`

但那给了我

buy helicopter //since there are twice "buy" and the number of total words is 2
adopt cute cat 

提前致谢。

Answer 1

只需在查询中添加AND phrases LIKE '%I want to buy car and then buy and adopt cute cat tomorrow.%'即可。它将使用FULLTEXT键快速查找匹配项，然后对结果进行后置过滤，以确保短语列中存在完全匹配的短语。
