使用弹性搜索从文本中提取关键字多词并返回搜索词的偏移量

如何解决使用弹性搜索从文本中提取关键字多词并返回搜索词的偏移量

我想从查询中提取很多关键字，并告诉关键字在该文本中的位置（偏移量） 所以这是我的进步，我创建了两个自定义分析器关键字和带状疱疹：

{
  "settings": {
    "analysis": {
      "analyzer": {
        "my_analyzer_keyword": {
          "type": "custom","tokenizer": "keyword","filter": [
            "asciifolding","lowercase"
          ]
        },"my_analyzer_shingle": {
          "type": "custom","tokenizer": "standard","lowercase","shingle"
          ]
        }
      }
    }
  },"mappings": {
    "your_type": {
      "properties": {
        "keyword": {
          "type": "string","index_analyzer": "my_analyzer_keyword","search_analyzer": "my_analyzer_shingle"
        }
      }
    }
  }

这里是我说的关键词：

{
  "hits": {
    "total": 2000,"hits": [
      {
        "id": 1,"keyword": "python programming"
      },{
        "id": 2,"keyword": "facebook"
      },{
        "id": 3,"keyword": "Microsoft"
      },{
        "id": 4,"keyword": "NLTK"
      },{
        "id": 5,"keyword": "Natural language processing"
      }
    ]
  }
}

我做了一个这样的查询：

{
  "query": {
    "match": {
      "keyword": "I post a lot of things on Facebook and quora"
    }
  }
}

所以我得到了上面的代码

{
  "took": 6,"timed_out": false,"_shards": {
    "total": 5,"successful": 5,"Failed": 0
  },"hits": {
    "total": 4,"max_score": 0.009332742,"hits": [
      {
        "_index": "test","_type": "your_type","_id": "2","_score": 0.009332742,"_source": {
          "id": 2,"keyword": "facebook"
        }
      },{
        "_index": "test","_id": "4","_score": 0.009207102,"_source": {
          "id": 4,"keyword": "quora"
        }
      }
    ]
  }
}

但我不知道文本中的词是那些词的偏移量： 我想知道 quora 从索引 40 开始。但不要在标签或类似的东西之间突出显示它们。

我想提一下，我的帖子是基于这个帖子
