Java Elasticsearch查询字符串查询不使用同义词分析器

我正在尝试使用同义词配置弹性搜索

以下是我的设置：

                "analysis": {
                    "analyzer": {
                        "category_synonym": {
                            "tokenizer": "whitespace",
                            "filter": [
                                "synonym_filter"
                            ]
                        }
                    },
                    "filter": {
                        "synonym_filter": {
                            "type": "synonym",
                            "synonyms_path": "synonyms.txt"
                        }
                    }
                }

映射配置：

        "category": {
            "properties": {
                "name": {
                    "type":"string",
                    "search_analyzer" : "category_synonym",
                    "index_analyzer" : "standard",
                    "fields": {
                        "raw": {
                            "type":  "string",
                            "index": "not_analyzed"
                        }
                    }
                }
            }
        }

还有我的同义词列表

film => video,
ooh => panels , poster,
commercial => advertisement,
print => magazine

我必须说我使用的是ElasticSearchJavaAPI。 我使用QueryBuilders.queryStringQuery，因为这是我为请求设置分析器的唯一方法。 因此，当我制作：

QueryBuilders.queryStringQuery("name:film").analyzer(analyzer)

它还我

[
  {
    "id": 71,
    "name": "Pitch video",
    "description": "... ",
    "parent": null
  },
  {
    "id": 25,
    "name": "Video",
    "description": "... ",
    "parent": null
  }
]

这对我来说太完美了，但当我打电话给这样的事情时

QueryBuilders.queryStringQuery("name:vid").analyzer(analyzer)

我希望它应该返回相同的对象，但没有任何内容：[]

因此，我在queryStringQuery中添加了星号：

很好，但是现在

QueryBuilders.queryStringQuery("name:film*").analyzer(analyzer)

返回我[]

那么，如何配置弹性搜索，使其在搜索视频、视频、胶片和胶片时返回相同的对象呢

提前谢谢

嗯，我认为Elasticsearch不知道如何将fil翻译成vid:-。所以，我认为您需要EdgeGrams来实现这一点，无论是在索引还是搜索时
