Solr Range Facets根据搜索查询动态修改范围 [英] Solr Range Facets dynamically modifying the ranges based on the search query

问题描述

这就是我正在尝试做的. 我在价格字段上定义了一个方面.

So here is what I am trying to do. I have a facet defined on the price field.

1)当查询"wordA"时 我希望各个方面介于0-1000之间，分为5个间隔，因为"wordA"的最高价格永远不会超过1000

1) When there is a query for "wordA" I want the facets to be from 0-1000 divided in 5 intervals since my maximum price for "wordA" will never exceed 1000

2)当查询"wordB"时 我希望将方面从0-50分为5个间隔，因为查询"wordB"的最高价格永远不会超过50.

2) When there is a query for "wordB" I want the facets to be from 0-50 divided in 5 intervals since my maximum price for the query "wordB" will never exceed 50.

因此，基本上，我希望构面范围能够动态变化，以使查询"wordB"的最终匹配范围不会在0-1000范围内，而所有匹配均位于第1个范围内.

So basically I want the facet range to change dynamically so that I don't end up with a range of 0-1000 for a query "wordB" where all the hits will lie in the 1st range.

如果solr不支持此功能，那么根据返回的结果来修改范围将涉及大量查询后处理.

If solr does not support this then it will be a lot of query post processing involved to modify the ranges based on the returned results.

推荐答案

Solr不支持此功能，但是您可以通过执行两个查询来自己完成操作-第一个

Solr does not support that, but you can do it yourself by doing two queries - first get the stats (max, min) for the field, then submit a query for the facet ranges (intervals) that are suitable for your application.
