弹性搜索可获取多个模型的所有记录

Question

I have two separate objects authors and publishers . How can I use elasticsearch to get all of both types?

I know I can do the following to search both:

Elasticsearch::Model.search('foo', [Author, Publisher])

But how do I get that to return all records?

Answer 1

Sorry, misread the question in my original answer.

To match all documents do:

response = Elasticsearch::Model.search('{ "query": { "match_all": {} } }', [Author, Publisher])
