ruby-on-rails - Rails + Sunspot : Multiple model search, 但只有其中一个型号的某些字段？

Question

在我的 Rails 应用程序中，我使用 Sunspot 来索引几个不同的模型。然后我有一个返回混合结果的全局搜索表单。这工作正常:

Sunspot.search(Person, EmailAddress, PhoneNumber, PhysicalAddress) do
  fulltext params[:q]
  paginate :per_page => 10
end

我想在此搜索中添加一个额外的模型，比如 Project。项目模型有相当多的索引:

class Project < ActiveRecord::Base
  searchable do
    string :category do
      category.name.downcase if category = self.category
    end

    string :client do
      client.name.downcase if client = self.client
    end

    string :status

    text :tracking_number
    text :description

    integer :category_id, :references => Category
    integer :client_id, :references => Client
    integer :tag_ids, :multiple => true, :references => Tag

    time :created_at, :trie => true
    time :updated_at, :trie => true
    time :received_at, :trie => true
    time :completed_at, :trie => true
  end
end

如何修改我原来的 Sunspot.search仅通过 tracking_number 调用添加搜索项目记录字段而不是 description field ？

Answer 1

Sunspot.search(Person, EmailAddress, PhoneNumber, PhysicalAddress, Project) do
  fulltext params[:q] do
    fields(:tracking_number, :other_fields_outside_your_project_model)
  end

  paginate :per_page => 10
end

这将对 tracking_number 字段和您指定的任何其他字段进行全文搜索，特别是在您的 Person、EmailAddress、PhoneNumber 和 PhysicalAddress 模型中。
