Following new ES5 doc:

[https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-percolate-query.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-percolate-query.html)

says 2 mapping must be defined: doctype, queries

doctype mapping is there to set what fields can be used in percolate query, if I want to be able to use every field available for an index, Can I re-use the index mapping or I need to duplicate the mapping?

Hey,

so `doctype` is just used as an example here, you can replace it with your own type.

great, Thanks!

I supposed it, but the documentation kind of suggest otherwise, even some examples have same confusion:

> **[Using the new elasticsearch 5 percolator - Luminis Amsterdam](https://amsterdam.luminis.eu/2016/10/13/using-the-new-elasticsearch-5-percolator/)**
>
> In the upcoming version 5 of elasticsearch the implementation for the percolator has changed a lot. They moved the percolator from being a separate endpoint and API to being a member of the search API. In the new version you can execute a percolator...
