Elasticsearch索引Postgres int4range范围

Question

I have a range field named salary of type int4range for my Postgres database. 我有一个名为范围字段salary类型int4range我的Postgres数据库。 I intend to index this field to Elasticsearch. 我打算将此字段索引到Elasticsearch。 May I know what is the recommended way to do this? 我可以知道推荐的方法吗？ From what I know there is no range type in Elasticsearch, only integer. 据我所知，Elasticsearch中没有范围类型，只有整数。

So, do I need to parse int4range's begin and end boundary individually and index them as salary_begin and salary_end and while searching use the range filter, or is there a better approach? 因此，我是否需要分别解析int4range的开始和结束边界并将它们索引为salary_begin和salary_end并在搜索时使用范围过滤器，还是有更好的方法？

Postgres ==> int4range ==> salary (only 1 field in PSQL)

Elasticsearch ==> integer ==> [salary_begin, salary_end] (2 index fields in ES)

Answer 1

No need to parse anything. 无需解析任何内容。 Just use lower() and upper() : 只需使用lower()和upper() ：
