使用gem Tire和ElasticSearch构建正确的搜索请求

我正在尝试为我的Flower Store实现简单的搜索请求,但由于我是Tire和ElasticSearch的新手,我无法理解如何做到这一点。

我有可搜索的模型Product和habtm模型CategoryColourFlower。我想要的是每个关联的复选框,产生类似于此的请求:

http://example.com/search?q=some%20query&category_names[]=bouquet&category_names[]=marriage&colour_names[]=red&colour_names[]=yellow&colour_names[]=white&flower_names[]=rose&flower_names[]=tulip&price_min=100&price_max=1000

但我只需要展示那些产品:

a) prestent in any of the requested categories (OR);
b) have all of the requested colours (AND);
c) have all of the requested flowers (AND);
d) enter the price range between price_min and price_max.

q参数用于在关联名称中搜索输入到文本字段的任何文本(例如,red roses bouquet),并使用上限标准显示它。

现在我只有

class Product
  include Mongoid::Document

  include Tire::Model::Search
  include Tire::Model::Callbacks

  has_and_belongs_to_many :categories
  has_and_belongs_to_many :colours
  has_and_belongs_to_many :flowers

  def self.search(params)
    tire.search(load: true, page: params[:page], per_page: 8) do |search|
      search.query  { string params[:query] } if params[:query].present?
    end
  end

  def to_indexed_json
    self.to_json(methods: [:category_names, :colour_names])
  end

  def category_names
    self.categories.collect { |c| c.name }
  end

  def colour_names
    self.colours.collect { |c| c.name }
  end
end

并且不知道如何配置它。我读到了filtersfacets,但由于英语不是我的母语,我无法理解它是什么以及如何使用它们。

我这样做了:

def self.search(params)
  tire.search(load: true, page: params[:page], per_page: 8) do
    query do
      boolean do
        must { string params[:query], default_operator: "AND" } if params[:query].present?
        must { string params[:category_names] } if params[:category_names].present?
        must { string params[:colour_names], default_operator: "AND" } if params[:colour_names].present?
        must { range :price, { gte: params[:price_min], lte: params[:price_max] } } if params[:price_min].present? && params[:price_max].present?
      end
    end

    # raise to_curl
  end
end
