1、搜索发帖日期为2017-01-01,或者帖子ID为XHDK-A-1293-#fJ3的帖子,同时要求帖子的发帖日期绝对不为2017-01-02
select * from forum.article where (post_date='2017-01-01' or article_id='XHDK-A-1293-#fJ3') and post_date!='2017-01-02' GET /forum/article/_search { "query": { "constant_score": { "filter": { "bool": { "should": [ {"term": { "postDate": "2017-01-01" }}, {"term": {"articleID": "XHDK-A-1293-#fJ3"}} ], "must_not": { "term": { "postDate": "2017-01-02" } } } } } } }
must,should,must_not,filter:必须匹配,可以匹配其中任意一个即可,必须不匹配
2、搜索帖子ID为XHDK-A-1293-#fJ3,或者是帖子ID为JODL-X-1937-#pV7而且发帖日期为2017-01-01的帖子
select * from forum.article where article_id='XHDK-A-1293-#fJ3' or (article_id='JODL-X-1937-#pV7' and post_date='2017-01-01') GET /forum/article/_search { "query": { "constant_score": { "filter": { "bool": { "should": [ { "term": { "articleID": "XHDK-A-1293-#fJ3" } }, { "bool": { "must": [ { "term":{ "articleID": "JODL-X-1937-#pV7" } }, { "term": { "postDate": "2017-01-01" } } ] } } ] } } } } }
3、梳理学到的知识点
(1)bool:must,must_not,should,组合多个过滤条件
(2)bool可以嵌套
(3)相当于SQL中的多个and条件:当你把搜索语法学好了以后,基本可以实现部分常用的sql语法对应的功能
