Question

我有两个索引的模型用于搜索（用户和项目）。我正在尝试跨模型进行地理搜索：

ThinkingSphinx::Search.search('keywords', :geo => [ degrees_to_radians(params[:lat].to_f), degrees_to_radians(params[:lon].to_f) ], )

但我只收到错误：

Sphinx Error: index item_core,item_delta,user_core,user_delta: unknown latitude attribute ''

单独搜索每个模型的工作正常......但我不知道这里的问题是什么。以下是索引：

用户指数：

define_index do
    indexes [:first_name, :last_name], :as => :name
    indexes login
    indexes email
    indexes headline
    indexes description
    indexes business.name, :as => :business_name
    indexes [addresses.street_1, addresses.street_2, addresses.city, addresses.postal_code], :as => :address

    has created_at, :sortable => true
    has addresses.latitude, :as => :latitude, :type => :float
    has addresses.longitude, :as => :longitude, :type => :float    

    set_property :delta => true
  end

物品索引：

define_index do
    indexes title, :sortable => true
    indexes description
    indexes [address.street_1, address.street_2, address.city, address.postal_code], :as => :address
    indexes images.title, :as => :image_titles
    indexes images.description, :as => :image_descriptions
    indexes categories(:name), :as => :category_names    

    has price, :sortable => true
    has created_at, :sortable => true
    has address.latitude, :as => :latitude, :type => :float
    has address.longitude, :as => :longitude, :type => :float    
    has categories(:id), :as => :category_ids

    where "`items`.`state` = 'for_sale'"

    set_property :delta => true    
  end

这是一个迟到的回应，但总比没有好，希望如此：

当您没有搜索特定模型时，Thinking Sphinx没有参考点来了解可用的属性，因此您需要明确告诉它使用的lat和long属性：

ThinkingSphinx::Search.search('keywords',
  :geo => [
    degrees_to_radians(params[:lat].to_f),
    degrees_to_radians(params[:lon].to_f)
  ],
  :latitude_attr  => "latitude",
  :longitude_attr => "longitude"
)

如何使用ThinkingSphinx对多个模型进行地理搜索？
