mysql - 如何获取选择查询选择结果的关键字？

Question

如何通过在 MySQL 中使用全文搜索 MATCH() AGAINST() 来获取选择查询选择结果集的确切关键字

SELECT ... , MATCH(table_column) AGAINST("'LIST_OF_KEYWORDS' IN BOOLEAN MODE") AS relevance

现在在这里我想获得完全匹配的关键字

Answer 1

From MySQL docs:

Find rows that contain the exact phrase “some words” (for example, rows that contain “some words of wisdom” but not “some noise words”). Note that the “"” characters that enclose the phrase are operator characters that delimit the phrase. They are not the quotation marks that enclose the search string itself.

Find exact phrase:

SELECT * FROM your_table 
WHERE MATCH(table_column) AGAINST('"PUT_YOUR_PHRASE"' IN BOOLEAN MODE) AS relevance

Find at least one of the keywords:

SELECT * FROM your_table 
WHERE MATCH(table_column) AGAINST('KEYWORD1 KEYWORD2' IN BOOLEAN MODE) AS relevance

Find at BOTH keywords:

SELECT * FROM your_table 
WHERE MATCH(table_column) AGAINST('+KEYWORD1 +KEYWORD2' IN BOOLEAN MODE) AS relevance
