范围聚合(Range Aggregation): 范围聚合用于将文档分组到指定的数值范围内,并计算每个范围的文档数量。 {"aggs": {"price_ranges": {"range": {"field":"price","ranges": [ {"from":0,"to":50}, {"from":50,"to":100}, {"from":100,"to":200} ...
如通过 terms aggregations 替代 range aggregations, 如要根据年龄来分组,分组目标是: 少年(14岁以下) 青年(14-28) 中年(29-50) 老年(51以上), 可以在索引的时候设置一个age_group字段,预先将数据进行分类。从而不用按age来做range aggregations, 通过age_group字段就可以了。
elasticsearch结合kibana、Logstash、Beats,也就是elastic stack(ELK)。被广泛应用在日志数据分析、实时监控等领域: 而elasticsearch是elastic stack的核心,负责存储、搜索、分析数据。 初识elasticsearch 1. elasticsearch背景介绍 elasticsearch底层是基于lucene来实现的。
