使用 ngram 分析器获取脏结果以进行高亮搜索

如何解决使用 ngram 分析器获取脏结果以进行高亮搜索

嗨，我正在使用最小长度为 1 和最大长度为 100 的 ngram，我正在获取文档并突出显示文档中的字段。现在，当我从 ES 获得结果时，即使大小为 10，它也有一些随机文档。并且该文档的相关分数也很高。有人可以让我知道如何从我的搜索结果中减少非相关文档。搜索文本，例如“samsung inc”得到“ach”的结果。但是当我在没有任何空间的情况下进行搜索时，我得到了预期的结果。

我使用了这些设置

{
    "settings": {
        "analysis": {
            "filter": {
                "ngram_filter": {
                    "type": "ngram","min_gram": 1,"max_gram": 101
                }
            },"analyzer": {
                "ngram_analyzer": {
                    "type": "custom","tokenizer": "standard","filter": [
                        "lowercase","ngram_filter"
                    ]
                }
            }
        },"max_ngram_diff": 101
    }
}

搜索查询：

    {
    "from": 0,"size": 10,"query": {
        "bool": {
            "must": [

                    }

                },{
