[Elasticsearch] 控制相关度 (六) - function_score查询中的filter,functions及random_score参数 本章翻译自Elasticsearch官方指南的Looking at Time一章。 时间数据处理(Looking at Time) 如果在ES中,搜索是最常见的行为,那么创建日期柱状图(Date Histogram)肯定是第二常见的。为什么要使用日期柱状图呢? 想象在你的数据...

function\_score 在Elasticsearch 中function_score是用于处理文档分值的 DSL,它会在查询结束后对每一个匹配的文档进行一系列的重打分操作,最后以生成的最终分数进行排序。它提供了几种默认的计算分值的函数: weight:设置权重 field_value_factor:将某个字段的值进行计算得出分数。
