使用Thinking Sphinx进行多个索引的全局搜索

ThinkingSphinx::Index.define :article, :with => :active_record do
  # fields
  indexes title, content
  # attributes
  has created_at
end

ThinkingSphinx::Index.define :user, :with => :active_record do
  # fields
  indexes name, email
  # attributes
  has created_at
end

results = ThinkingSphinx.search "search keyword", :indices => [:article, :user]

results.each do |result|
  case result.class.to_s
  when "Article"
    puts result.title
  when "User"
    puts result.name
  end
end
