elasticsearch - Elasticsearch 从突出显示中排除“停止”词

Question

我想从突出显示中排除默认停用词，但我不确定为什么这不起作用

ES 配置

"settings": {
    "analysis": {
        "analyzer": {
            "search_synonyms": {
                "tokenizer": "whitespace",
                "filter": [
                    "graph_synonyms",
                    "lowercase",
                    "asciifolding",
                    "stop"
                ],
            }
        },
        "filter": {
            "graph_synonyms": {
                ...
            }
        },
        "normalizer": {
            "normalizer_1": {
                ...
            }
        }
    }
},

字段映射：

"mappings": {
    "properties": {
        "description": {
            "type": "text",
            "analyzer": "search_synonyms"
        },
        "narrative": {
            "type":"object",
            "properties":{
                "_all":{
                    "type": "text",
                    "analyzer": "search_synonyms"
                }
            }
        },
        "originator": {
            "type": "keyword",
            "normalizer": "normalizer_1"
        },
        ................
    }
}

高亮查询：

highlight : {
    fields:{
        "*":{}
    }
},

目前，我在叙述字段中突出显示了停用词，例如this, A，IS我想防止这种情况发生。
