我如何按照solr / lucene中的字段分组摘录？

Question

当我在Solr中索引以下文档时：

[
  {
    "id" : "978-0641723445",
    "name" : "The Lightning Thief",
    "author" : "Rick Riordan",
    "series_t" : "Rick Jackson and the Olympians",
  }
,
  {
    "id" : "978-1423103349",
    "cat" : ["book","paperback"],
    "name" : "The Sea of Monsters",
    "author" : "Rick Riordan",
    "series_t" : "Rick Jackson and the Olympians",
  }
]

并运行以下查询： http://localhost:8983/solr/gettingstarted/select?hl.fl=name&hl=on&indent=on&q=rick&rows=20&wt=json

我希望有一个摘录，其中包含每个匹配字段的名称和字段内容的子摘录（子摘录的实际格式不是那么重要）：

"responseHeader": {
    "status": 0,
    "QTime": 1,
    "params": { ...
    },
    "response": {
        "numFound": 2,
        "start": 0,
        "docs": [{
                "id": "978-0641723445",
                .. {
                    "id": "978-1423103349",
                    ..
                }],
            "highlighting": {
                "978-0641723445": {
                    "author": "Rick Riordan",
                    "series_t": "Rick Riordan and..."
                },
                "978-1423103349": {
                    "author": "Rick Riordan",
                    "series_t": "Rick Riordan and..."

                }
            }
        }
    }

如何更改solr查询以完成此操作？或者这种变化是否需要定制的solr / lucene荧光笔？
