Elasticsearch的多面過濾器

Question

如何將多個過濾器應用於facet（帶輪胎寶石）？我有一個代碼：

facet "packages" do 
    terms :package 
    facet_filter :terms, producer: [*params[:producer]] if params[:producer].present? 
    facet_filter :terms, category_id: [*params[:category_id]] if params[:category_id].present? 
end 

但它似乎只適用於最後一個過濾器。但我需要他們兩個。

Answer 1

試試這個

my_filter = [] 
my_filter << {:terms => {:producer => [*params[:producer]] }} if params[:producer].present? 
my_filter << {:terms => { :producer => [*params[:category_id]] }} if params[:category_id].present? 

facet "packages" do 
    terms :package 
    facet_filter :and, my_filter 
end 

Answer 2

my_filter = [] 
my_filter << {:term => {:producer => params[:producer] }} if params[:producer].present? 
my_filter << {:term => {:category_id => params[:category_id] }} if params[:category_id].present? 

facet "packages" do 
    terms :package 
    facet_filter(:and, my_filter) if my_filter.present? 
end
