Question

可以对以下solr集合执行查询

{
    "id":1,
    "book_name":"Solr book",
    "category":[1,2,3],
    "author":[1]
},
{
    "id":1,
    "book_name":"Rocky",
    "category":[3],
    "author":[2]
},
{
    "category_id": 1,
    "category_name":"Technology"
},
{
    "category_id": 2,
    "category_name":"Apache Lucene"
},
{
    "category_id": 3,
    "category_name":"Sport"
},
{
    "author_id": "1",
    "author_name" "Chuck Norris"
},
{
    "author_id": "1",
    "author_name" "John Rambo"
}

将返回类似的内容：

{
    "id": 1,
    "book_name": "Solr book",
    "categories": ["Technology", "Apache Lucene"],
    "Authors": ["Chuck Norris"]
}

在典型的Searchbox输入中按book_name和/或category_name AND / OR作者名称进行搜索？或另一种回应，我将返回类似的东西？

否则这是实现它的首选解决方法/最佳实践？

...我们希望通过前端Web应用执行单个查询，不使用使用Backend Web App来构建响应，因为该数据已经在solr中。

我确定收藏的方式是错误的，我是这样做的：

<dataConfig>
  <dataSource type="JdbcDataSource"
            driver="com.mysql.jdbc.Driver"
            url="jdbc:mysql://localhost:3306/circulo_lectores"
            user=""
            password="" /> 
  <document>
        <entity name="book" query="SELECT * FROM book">

            <field column="id" name="id"/>
            <field column="book" name="book" />

            <entity name="book_author" query="SELECT * FROM book_author WHERE book_id= ${book.id}">         
                <field column="author_id" name="author_id" />
                <entity name="author" query="select * FROM author WHERE id = ${book_author.author_id}">
                    <field column="author_name" name="author_name" />
                </entity>                   
            </entity>   

            <entity name="book_category" query="SELECT * FROM book_category WHERE book_id= ${book.id}">         
                <field column="category_id" name="category_id" />
                <entity name="category" query="select * FROM category WHERE id = ${book_category.category_id}">
                    <field column="category_name" name="category_name" />
                </entity>                   
            </entity>               

        </entity>   
  </document>
</dataConfig>

这reference给了我线索。希望它有助于其他人
