Elasticsearch应该操作查询

Question

我怎么能暗示＆＃34;应该＆＃34;操作 （＆＃34;标记＆＃34; =＆＃34; A＆＃34; OR＆＃34;标记＆＃34; =＆＃34; B＆＃34;）和＆＃34;名称＆＃34; =＆＃34 ;猫＆＃34;

喜欢？

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

。必须（QueryBuilders.matchQuery（＆＃34;名称＆＃34;＆＃34;猫＆＃34））;

Answer 1

如果您想("tag"="A" OR "tag"="B") and "name"="cat"，请执行以下操作：

 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"));
