elasticsearch - Elasticsearch精确突出显示

Question

我想将突出显示的文本作为突出显示的单词列表而不是整个文本或片段来接收。

我的查询是渗滤器查询:

{'doc': {'field_name': text}, "highlight": {
        "fields": {
            "field_name": {}
        }
    }, 'size': 100}

例如，默认情况下，我收到

field_name: ['some text ...<em>word1</em> ... some text ...<em>word2</em> some text...']

我想收到:

field_name: ['word1', 'word2']

我该怎么做？

Answer 1

  "highlight": {
    "fields": {
      "field_name": {
        "fragment_size": q,
        "number_of_fragments": 100
      }
    }
  }

会成功的
