How do I merge two or more results from elasticsearch rails gem? - elasticsearch

Question

I'm trying to merge two elasticsearch results into one variable, here my code tries...
class SearchController < ApplicationController
def index
end
def advanced
#results = {}
if !params[:fast_search].empty?
#results[:features] = TestCases.search(params[:fast_search]).results
#results[:steps] = Steps.search(params[:fast_search]).results
#results[:examples] = Examples.search(params[:fast_search]).results
else
unless params[:feature].blank?
features = TestCases.search(query: { match: { function: params[:feature] } }).results
features_tag = Steps.search(query: { match: { tags: params[:tags] } }).results
#results[:features] = features + features_tag
end
unless params[:steps].blank? || params[:scenario].blank?
#results[:steps] = Steps.search(query: { match: { scenario: params[:scenario] } }).results
params[:steps].each do |step|
#results[:steps] += Steps.search(query: { match: { steps: step } }).results
end
#results[:steps] += Steps.search(query: { match: { tags: params[:tags] } }).results
end
unless params[:examples].blank?
params[:examples].each do |example|
#results[:examples] += Examples.search(query: { match: { examples: example } }).results
end
#results[:examples] += Examples.search(query: { match: { tags: params[:tags] } }).results
end
unless params[:bug].blank?
#results[:miscs] = StepsMiscs.search(query: { match: { bug: true } }).results
end
end
render "search/index"
end
end
I also try features.merge(features_tag) but no success either.
It's simple, I just need to merge one and more results from the elasticsearch, but I simply don't know how.
Here's my Gemfile:
source 'https://rubygems.org'
# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '~> 5.0.0', '>= 5.0.0.1'

end
# Windows does not include zoneinfo files, so bundle the tzinfo-data gem
gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw, :jruby]
And here's obviously the error that I'm getting:
undefined method `+' for #<Elasticsearch::Model::Response::Results:0x0000000d2719f8>
Thanks!

Here after a lot of search, I've found this:
unless params[:steps].blank? || params[:scenario].blank? || params[:tags].blank?
query = Jbuilder.encode do |json|
json.query do
json.match do
json.scenario do
json.query params[:scenario]
end
end
params[:steps].each do |step|
json.match do
json.tags do
json.query step
end
end
end
json.match do
json.tags do
json.query params[:tags]
end
end
end
end
#results[:steps] = Steps.search(query).results
end
This help me to search more than one match on all my models.
I know that catch only the basics, but at the moment is part for what I need and I hope this could help all the others around here with the same issue!
Thanks you all!
