ElasticSearch Highlight Behavior

/ 29 сентября 2019

Я использую подсветку ElasticSearch, и поведение сбивает с толку.

Ниже приведен мой документ, который проиндексирован: 

POST clients_with_lemma_policy_document_type_en-us/doc/D1OoeG0B0rPisNgfCVyL
    {
  "query": {
    "bool": {
      "should": [
        {
          "query_string": {
            "query": """(NOT(isLemmatisationEnabled : 1) AND "knives") OR ((isLemmatisationEnabled : 1) AND "knife")"""
          }
        }
      ],
      "minimum_should_match": 1
    }
  },
  "phraseConfigVersion": 0,
  "mode": "BLACKLISTING",
  "metadataInformation": {
    "category": "offensive"
  },
  "phrases": [
    "knives"
  ],
  "lemmas": [
    "knife"
  ]
}

И это мой поиск: 

GET clients_with_lemma_policy_document_type_en-us/_search/
{
  "query": {
    "percolate": {
      "field": "query",
      "document": {
        "mainText": [
          "I have too many knives!!! knife."
        ],
        "subText": "I have too many knives knife kill."
      }
    }
  },
  "highlight": {
    "number_of_fragments": 0,
    "fields": {
      "*": {
        "pre_tags": [
          "<em>"
        ],
        "post_tags": [
          "</em>"
        ]
      }
    }
  },
  "size": 10000
}

Результат:

Почему подсвечивается «нож», хотя входной документ не содержит флаг isLemmatisationEnabled?
