I am using elasticsearch-rails and elasticsearch-model gem for searching words in my rails app.

Here is my model article.rb where I want to search to take place:

require 'elasticsearch/model'

class Article < ActiveRecord::Base
  include Elasticsearch::Model
  include Elasticsearch::Model::Callbacks

  def self.search(query)
    __elasticsearch__.search(
      {
        query: {
          multi_match: {
            query: query,
            fuzziness: 2,
            fields: ['title^10', 'text']
          }
        },
        highlight: {
          pre_tags: ['<em>'],
          post_tags: ['</em>'],
          fields: {
            title: {},

          }
        }
      }
    )
  end
end

Here is my model controller search_controller.rb

class SearchController < ApplicationController

  def search
    if params[:q].nil?
      @articles = []
    else
      @articles = Article.search params[:q]
      logger.info "LocationController.add_locations called with params: #{@articles.records.each_with_hit { |record, hit| puts "* #{record.title}: #{hit._score}" }}"
    end
  end
end

I am getting search results. But my question is : If I search for "John team".

Articles.search('John team').records.records

I get multiple records with perfect match 'john team' and some matches related to 'john' or 'team'.

but I want , if 'john team' is perfectly match in my database the result should only john team.I don't want another records.but if 'john team' is not present I want another results related to 'john' or 'team' both keywords.

example:

Article.search('John team').records.records
responce: ('john team', 'team joy', 'John cena')

But I want 

   Article.search('John team').records.records
    responce: ('john team')

Try this if you want to match both the words and not any single word

  def self.search(query)
    __elasticsearch__.search(
      {
        query: {
          multi_match: {
            query:{ match: {content: {query: query, operator: "and" }}},
            fuzziness: 2,
            fields: ['title^10', 'text']
          }
        },
        highlight: {
          pre_tags: ['<em>'],
          post_tags: ['</em>'],
          fields: {
            title: {},

          }
        }
      }
    )
  end
