Mysql find keywords in text

问题

I have a Mysql InnoDB table with 10k keywords and I want to match them against several texts.

Some keywords have several words and I only want exact matchs.

Example: Keywords - brown fox, lazy cat, dog, fox, rabbit

Text - The quick brown fox jumps over the lazy dog

I want the query to return - brown fox, dog, fox

回答1:

SELECT * FROM tenKTable 
WHERE 'The quick brown fox jumps over the lazy dog' LIKE CONCAT('%',keyword,'%')

Source: MySQL SELECT query string matching

回答2:

Here's one idea:

SELECT keyword 
FROM Keywords
 JOIN (SELECT 'The quick brown fox jumps over the lazy dog' as col) k
   on k.col like Concat('%',keywords.keyword,'%')

And the SQL Fiddle.

Good luck.
