启用关键字类型的数字的升序和降序排序（Elasticsearch）

Question

我的任务是按升序和降序对文档进行排序，但'number'必须保留关键字类型。我阅读了关于类似主题的其他帖子，并尝试添加一个 'number' 类型的整数，但我没有成功，索引崩溃了。我在 esMapping.js 文件中附加了当前配置。

有没有办法修复此 esMapping.js 文件，以便升序和降序排序正常工作？

"settings": {
    "analysis": {
        "analyzer": {
            "document_number_analyzer": {
                "type": "custom",
                "tokenizer": "document_number_tokenizer"
            }
        },
        "tokenizer": {
            "document_number_tokenizer": {
                "type": "pattern",
                "pattern": "-0*([1-9][0-9]*)\/",
                "group": 1
            }
        },
    }
}

映射：

"number": {
            "type": "keyword",
            "copy_to": [
                "_summary"
            ],
            "fields": {
                "sequenceNumber": {
                    "type": "text",
                    "analyzer": "document_number_analyzer"
                }
            }
        }

使用整数子字段对文档进行排序后出错：

你的映射需要像这样：

    "number": {
        "type": "keyword",
        "copy_to": [
            "_summary"
        ],
        "fields": {
            "sequenceNumber": {
                "type": "integer"
            }
        }
    }

然后您可以简单地按 number.sequenceNumber
