Solr查询匹配嵌套/关系数据

Question

我正在使用apache solr来获取我的webapp的匹配功能,我遇到了这种情况的问题:

我有三个程序员,技能领域是他们的技能,"重量"意味着他/她的技能有多好:

{
    name: "John",
    skill: [
        {name: "java", weight: 90},
        {name: "oracle", weight: 90},
        {name: "linux", weight: 70}
    ]
},
{
    name: "Sam",
    skill: [
        {name: "C#", weight: 98},
        {name: "java", weight: 75},
        {name: "oracle", weight: 70},
        {name: "tomcat", weight: 70},
    ]
},
{
    name: "Bob",
    skill: [
        {name: "oracle", weight: 90},
        {name: "java", weight: 85}
    ]
}

我找工作的程序员:

{
    name: "webapp development",
    skillRequired: [
        {name: "java", weight: 85},
        {name: "oracle", weight: 85},
    ]
}

我想用这份工作的"技能要求"来匹配那些程序员(找到最适合这份工作的人).在这种情况下,应该是John和Bob,Sam因为他的java和oracle技能不够好而被踢掉了.约翰应该比鲍勃得分更高,因为他更了解甲骨文.

问题是,solr无法索引嵌套对象,我认为我能得到的最佳格式是:

name: "John",
skill-name: ["java", "oracle", "linux"],
skill-weight: [90, 90, 70]

等等.所以我不知道是否可以构建一个查询来使这个场景工作.

是否有更好的架构结构？或使用索引/查询时间提升？

我读了几乎所有的solr wiki和google,没有运气,欢迎任何提示和解决方法.

问题解决了,请在此处记录我的解决方

1,我的数据格式是json,所以我需要solr-4.8.0来支持使用json的索引嵌套数据.如果数据是xml格式,solr-4.7.2仍然有效.

2,solr-4.8.0需要java7-u55(官方推荐)

3,嵌套文档/对象应该使用" childDocuments "键提交给solr .为了识别父/子文档的类型,我添加了"type"字段.所以上面的例子看起来像这样:

   {
        type: "programmer",
        name: "John",
        _childDocuments_: [
            {type:"skill", name: "java", weight: 90},
            {type:"skill", name: "oracle", weight: 90},
            {type:"skill", name: "linux", weight: 70}
        ]
    },
    {
        type: "programmer",
        name: "Sam",
        _childDocuments_: [
            {type:"skill",name: "C#", weight: 98},
            {type:"skill", name: "java", weight: 75},
            {type:"skill", name: "oracle", weight: 70},
            {type:"skill", name: "tomcat", weight: 70},
        ]
    },
    {
        type: "programmer",
        name: "Bob",
        _childDocuments_: [
            {type:"skill", name: "oracle", weight: 90},
            {type:"skill", name: "java", weight: 85}
        ]
    }

4,提交并提交到solr之后,我可以将作业与块连接查询匹配(在过滤查询中):

fq={!parent which='type:programmer'}type:skill AND name:java AND weight:[85 TO *]&
fq={!parent which='type:programmer'}type:skill AND name:oracle AND weight:[85 TO *]

您可以尝试BlockJoinQuery。参考这里
