如何获取与Elasticsearch中匹配的单词令牌

我需要匹配的单词值列表。如果我的搜索字符串为abc，它是我的名称，我的预期列出的是值列表[abcdef，abcdefgh，.. ...]

myd在

[
{'id':1,  'name': 'christiano ronaldo', 'description': 'portugal'},
{'id':2,  'name': 'lionel messi', 'description': 'argentina'},
{'id':3,  'name': 'Lionel Jr', 'description': 'brazil'}
]

DSL查询下方的MyD下方是

{
  "query": {
    "match_phrase_prefix": {
      "name": {
        "query": "lio",
        "slop": 3,
      }
    }
  }
}

我的输出下方

{'took': 2,
 'timed_out': False,
 '_shards': {'total': 1, 'successful': 1, 'skipped': 0, 'failed': 0},
 'hits': {'total': {'value': 2, 'relation': 'eq'},
  'max_score': 0.4700036,
  'hits': [{'_index': 'players',
    '_type': '_doc',
    '_id': '2',
    '_score': 0.4700036,
    '_source': {'id': 2, 'name': 'lionel messi', 'description': 'argentina'}},
   {'_index': 'players',
    '_type': '_doc',
    '_id': '3',
    '_score': 0.4700036,
    '_source': {'id': 3, 'name': 'Lionel Jr', 'description': 'brazil'}}]}}

，有任何方法可以提取

像我预期的那样匹配的令牌单词，只是lionel lio 匹配Lionel和Lionel的名称

原文

I need list of values of words which matches. if my search string is abc which is theere in my name of document my expected out is just list of values [abcdef, abcdefgh, .....]

myd is below

[
{'id':1,  'name': 'christiano ronaldo', 'description': 'portugal'},
{'id':2,  'name': 'lionel messi', 'description': 'argentina'},
{'id':3,  'name': 'Lionel Jr', 'description': 'brazil'}
]

DSL query is below

{
  "query": {
    "match_phrase_prefix": {
      "name": {
        "query": "lio",
        "slop": 3,
      }
    }
  }
}

My output is below

{'took': 2,
 'timed_out': False,
 '_shards': {'total': 1, 'successful': 1, 'skipped': 0, 'failed': 0},
 'hits': {'total': {'value': 2, 'relation': 'eq'},
  'max_score': 0.4700036,
  'hits': [{'_index': 'players',
    '_type': '_doc',
    '_id': '2',
    '_score': 0.4700036,
    '_source': {'id': 2, 'name': 'lionel messi', 'description': 'argentina'}},
   {'_index': 'players',
    '_type': '_doc',
    '_id': '3',
    '_score': 0.4700036,
    '_source': {'id': 3, 'name': 'Lionel Jr', 'description': 'brazil'}}]}}

is there any way to extract the token word which matches

Like my expected out is only is just lionel only as lio matches the name which is lionel and Lionel

据我所知，没有直接的方法可以在搜索结果中获得文本的匹配令牌。

但是，一种方法是使用 ighlighting 文本中的匹配术语。

{
    "query": {
        "match_phrase_prefix": {
            "name": {
                "query": "lio",
                "slop": 3
            }
        }
    },
    "highlight": {
        "fields": {
            "name": {}
        }
    }
}

您可以解析搜索结果响应，并在应用程序方面检索突出显示的术语。

As far as I'm aware, there is no direct way to get only the text's matched tokens in the search result.

However, one method is to use highlighting to get the matching terms in the text.

{
    "query": {
        "match_phrase_prefix": {
            "name": {
                "query": "lio",
                "slop": 3
            }
        }
    },
    "highlight": {
        "fields": {
            "name": {}
        }
    }
}

You can parse the search result response and retrieve the highlighted terms later on the application side.
