elasticsearch - Elasticsearch应该操作查询

Question

我该如何暗示“应该”操作
(“tag” =“A” OR“tag” =“B”)和“name” =“cat”

喜欢 ？

 BoolQueryBuilder queryBuilder = QueryBuilders.boolQuery()
.should(QueryBuilders.matchQuery("tag","A"))
.shold(QueryBuilders.matchQuery("tag","B"))

.must(QueryBuilders.matchQuery(“name”，“cat”)));

Answer 1

如果要执行("tag"="A" OR "tag"="B") and "name"="cat"，则可以执行以下操作:

 BoolQueryBuilder aOrB = QueryBuilders.boolQuery()
.should(QueryBuilders.matchQuery("tag","A"))
.should(QueryBuilders.matchQuery("tag","B"))

 BoolQueryBuilder queryBuilder = QueryBuilders.boolQuery()
.must(aOrB);
.must(QueryBuilders.matchQuery("name","cat"));
