例子一.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:必须匹配
should:可以匹配其中任意一个即可
must_not:必须不匹配
例子二.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"
}
}
]
}
}

- 1、bool:must,must_not,should,组合多个过滤条件
- 2、bool可以嵌套
