Question

我试图在SQL中执行与以下内容相同的弹性：

select * from Pets 
where type is 'cat'
and age > 10
and name in ("Barry", "Oscar", .....)

我有以下Java代码：

SearchRequest searchRequest = new SearchRequest(elasticIndexName);
BoolQueryBuilder queryBuilder = QueryBuilders.boolQuery();
queryBuilder.must(QueryBuilders.termQuery("type", "cat"));
queryBuilder.must(QueryBuilders.rangeQuery("age").from("10"));
queryBuilder.must(QueryBuilders.termQuery("name", "Oscar"));
queryBuilder.must(QueryBuilders.termQuery("name", "Barry"));

但是，如果我理解正确，最后两个＆＃34;必须＆＃34;陈述相互矛盾。我尝试使用＆＃34;应该＆＃34;这个术语似乎带来了所有猫的名字。

Answer 1

你几乎就在那里，你需要这样做（即使用terms查询）：

SearchRequest searchRequest = new SearchRequest(elasticIndexName);
BoolQueryBuilder queryBuilder = QueryBuilders.boolQuery();
queryBuilder.must(QueryBuilders.termQuery("type", "cat"));
queryBuilder.must(QueryBuilders.rangeQuery("age").from("10"));
queryBuilder.must(QueryBuilders.termsQuery("name", "Oscar", "Barry"));

Answer 2

而不是术语查询，我认为您应该尝试这一点，它会帮助您获得最佳效果。

BoolQueryBuilder boolQueryBuilder = boolQuery();
boolQueryBuilder.must(QueryBuilders.matchQuery("type", cat));
boolQueryBuilder.must(QueryBuilders.rangeQuery("age").gt(10));
boolQueryBuilder.must(QueryBuilders.multiMatchQuery(String.join(" ", Arrays.asList("Barry", "Oscar"), name).type(Type.BEST_FIELDS));

如何在ElasticSerch＆amp;中进行AND + OR查询Java的
