BoolQueryBuilder

// 等价SQL： shop_id=100 and status=3 or (price >= 100 and price <= 300)
BoolQueryBuilder boolQueryBuilder = QueryBuilders.boolQuery()
                .must(QueryBuilders.termQuery("shop_id", 100)) // 通过must设置term子查询
                .must(QueryBuilders.termQuery("status", 3)) // 通过must设置term子查询
                .should(QueryBuilders.rangeQuery("price").gte(100).lte(300));// 通过should设置range子查询
                
SearchRequest searchRequest = new SearchRequest();

// 通过SearchSourceBuilder构建搜索参数
SearchSourceBuilder builder = new SearchSourceBuilder();
// 设置query参数，绑定前面创建的Query对象
builder.query(boolQueryBuilder);

// 设置SearchRequest搜索参数
searchRequest.source(builder);
// 执行ES请求
SearchResponse searchResponse = client.search(searchRequest, RequestOptions.DEFAULT);

bool->must->bool->should

可以嵌套使用
