Question

我有以下型号。

class Author
    include Tire::Model::Search
    include Tire::Model::Callbacks

    has_many :books
    has_many :tags #(eg: 'german', 'philosopher')
end

class Book
    belongs_to :author
    belongs_to :book_type #(eg: 'paperback', 'hardcover')
    has_many :tags #(eg: 'crime', 'drama')
end

我需要帮助理解和编写以下搜索查询，

Find all authors who are tagged as 'german' AND 'philosopher'
                     have written at least 1 book each of book_type 'paperback' AND 'hardcover'
                     where each such book is tagged as 'crime' AND 'drama'

Find all authors who are tagged as 'german' AND 'philosopher'
                     have written at least 1 book of any book_type
                     where that book is tagged as 'crime' AND 'drama'

我添加了一个带有样本种子数据@ https://github.com/rahul/nested_tire_query_problem

的迷你导轨项目

更新

我试图在include books中为作者写一个映射作为'嵌套'类型。但是to_indexed_json方法会覆盖映射中的定义，并在作者中创建非嵌套书籍。

后端：MySQL（我使用to_indexed_json将文档提供给elasticsearch）

感谢任何帮助！
