Question

我正在尝试按照本指南创建索引：https://www.elastic.co/guide/en/elasticsearch/client/java-rest/master/java-rest-high-create-index.html#_providing_the_whole_source
问题是，该索引创建不正确。看起来整个settings部分以及completion类型都被忽略了。

我的json文件：

{
    "settings": {
        "number_of_shards": 3,
        "number_of_replicas": 1,
        "analysis": {
            "filter": {},
            "analyzer": {
                "keyword_analyzer": {
                    "filter": [
                        "lowercase",
                        "asciifolding",
                        "trim"
                    ],
                    "char_filter": [],
                    "type": "custom",
                    "tokenizer": "keyword"
                }
            }
        }
    },
    "mappings": {
        "my_type": {
            "properties": {
                "first": {
                    "type": "text",
                    "fields": {
                        "keywordstring": {
                            "type": "text",
                            "analyzer": "keyword_analyzer"
                        },
                        "completion": {
                            "type": "completion"
                        }
                    },
                    "analyzer": "standard"
                },
                "second": {
                    "type": "text",
                    "fields": {
                        "keywordstring": {
                            "type": "text",
                            "analyzer": "keyword_analyzer"
                        },
                        "completion": {
                            "type": "completion"
                        }
                    },
                    "analyzer": "standard"
                },
                "third": {
                    "type": "text",
                    "fields": {
                        "keywordstring": {
                            "type": "text",
                            "analyzer": "keyword_analyzer"
                        },
                        "completion": {
                            "type": "completion"
                        }
                    },
                    "analyzer": "standard"
                },
                "fourth": {
                    "type": "text",
                    "fields": {
                        "keywordstring": {
                            "type": "text",
                            "analyzer": "keyword_analyzer"
                        },
                        "completion": {
                            "type": "completion"
                        }
                    },
                    "analyzer": "standard"
                }
            }
        }
    }
}

Java代码：

CreateIndexRequest indexRequest = new CreateIndexRequest(ESClientConfiguration.INDEX_NAME);
        URL url = Resources.getResource(TERYT_INDEX_CONFIGURATION_FILE_NAME);

        return Try.of(() -> Resources.toString(url, Charsets.UTF_8))
                  .map(jsonIndexConfiguration -> indexRequest.source(jsonIndexConfiguration, XContentType.JSON))
                  .get();

createIndexRequest.setTimeout(TimeValue.timeValueMinutes(2));

        Try.of(() -> client.indices().create(createIndexRequest, RequestOptions.DEFAULT))...

索引已创建，但是当我查看索引元数据时，它看起来完全错误：

    "state": "open",
    "settings": {
        "index": {
            "creation_date": "1556379012380",

                        }
                    }

                        }

                            "type": "keyword"
                        }
                    }
                }
            }
        }
    },
    "aliases": [],

    },
    "in_sync_allocations": {
        "0": [

            "FcTUhpb_SL2LiaEyy_uwkg"
        ]
    }
}

只有1个没有副本的分片，我也没有看到有关completion类型的任何信息。有人可以告诉我我在做什么错吗？

我认为这一行：

    Try.of(() -> client.indices().create(createIndexRequest, RequestOptions.DEFAULT))...

隐藏了一个重要的例外。在这里，您使用的是Elasticsearch 7.0.0，它不再允许在映射中提供“类型”名称。

代替

"mappings": {
    "my_type": {
        "properties": {

您应该写：

"mappings": {
    "properties": {

由于该异常以及可能在创建索引之后就对某些文档建立索引这一事实，因此将应用默认的索引设置和映射。可以解释您所看到的内容。

您需要先修复索引设置。我建议在Kibana开发人员控制台中进行此操作。

弹性搜索，通过Rest Java Client使用源和设置创建索引
