ElasticSearch Java API之高级查询(分页查询,高亮查询,正则表达式查询,聚合查询等),ElasticSearch封装了很多查询方法首先我们需要批量插入数据,以做测试使用staticvoidb
3、bool复合查询: public static void booleanQuery1(String indexName,String indexType) { QueryBuilder qb = QueryBuilders.boolQuery() .must(QueryBuilders.matchQuery("title", "java")) .should(QueryBuilders.termQuery("title", "hadoop")) .mustNot(QueryBuilders.termQuery("title", "spring")); Se...
2.count(distinct) 查询 对应sql语句: select count(distinct user_id) from table1 es 查询例子: //筛选条件,查询全部数据 QueryBuilder queryBuilder = QueryBuilders.matchAllQuery(); //自定义distinct聚合函数 CardinalityAggregationBuilder cardinalityAgg = AggregationBuilders.cardinality("user_distinct").field...
