es 中如何实现 sql 中的in，使用terms实现
语法如下：
term: { "field": "value"}terms: { "field": ["value1", "value2"]} select * from tbl where col in ("value1", "value2") POST /forum/article/_bulk{ "update": { "_id": "1"} }{ "doc" : { "tag" : ["java", "hadoop"]} }{ "update": { "_id": "2"} }{ "doc" : { "tag" : ["java"]} }{ "update": { "_id": "3"} }{ "doc" : { "tag" : ["hadoop"]} }{ "update": { "_id": "4"} }{ "doc" : { "tag" : ["java", "elasticsearch"]} } GET /forum/article/_search { "query": { "constant_score": { "filter": { "terms": { "articleID": [ "KDKE-B-9947-#kL5", "QQPX-R-3956-#aD8" ] } } } }} 搜索tag中包含java的帖子
GET /forum/article/_search{ "query" : { "constant_score" : { "filter" : { "terms" : { "tag" : ["java"] } } } }} 查询返回结果
