查询语句：SELECT * FROM nlu_define_table WHERE JSON_CONTAINS(JSON_ARRAY("我","想","销","存单"),keywords->'$.keywords') ORDER BY weights DESC;

其他查询语句：

SELECT * FROM nlu_define_table;

SELECT * FROM nlu_define_table WHERE keywords LIKE "%销%";

SELECT * FROM nlu_define_table WHERE JSON_EXTRACT(keywords,'$.keywords') LIKE "%销%";

SELECT * FROM nlu_define_table WHERE keywords -> '$.keywords' LIKE "%销%";

第三条sql和第四条sql是等效。
