Fetching results in random order with a :where clause using searchkick and rails

Question

This is probably a simple thing, but I can't seem to get my head around it:

I want elasticsearch to return:

@random_books   = Book.search("*", where: { status: :published }, body: { query: { function_score: { random_score: { seed: seed }}}}, page: params[:page], per_page: 12)

The results returned do not honor the where: {status: :published} clause. How do I syntax up this query?

Edits: Found another question asking basically the same thing; without a working solution/answer of course.

Answer 1

Okay, here's the solution:

seed = Time.zone.now.to_i

@random_books   = Book
                    .search("*",
                      body: {
                        query: {
                          function_score: {
                            query: {
                              match: { status: :published }
                              },
                            random_score: {
                              seed: seed
                            }
                          }
                        }
                      },
                      page: params[:random],
                      per_page: 12)

Searchkick will ignore the options (like where: clause) if we pass body to elasticsearch. So we match the query inside of function_score as described here.

Easy-peasy.
