使用映射创建 Elasticsearch 索引

Question

我正在努力完成创建索引的简单任务，目标是创建一个带有分析器和字段映射的索引。当我使用分析器创建索引时，我可以通过分析 api 调用与分析器通信，但是当我添加映射信息时，创建索引调用失败并显示“找不到字段 [$field]] 的分析器 [analyzer1]”，我创建了一个脚本来显示问题:

    #!/bin/bash

    INDEX_NAME="test1"

    echo "delete index just to be sure"
    curl -XDELETE "http://localhost:9200/$INDEX_NAME/"; echo

    echo "create new index"
    curl -X PUT "http://localhost:9200/$INDEX_NAME/" -d '{
        "index":{
            "analysis":{
                "analyzer":{
                    "analyzer1":{
                        "type":"custom",
                        "tokenizer":"standard",
                        "filter":[ "standard", "lowercase", "stop", "kstem", "ngram" ]
                    }
                },
                "filter":{
                    "ngram":{
                        "type":"ngram",
                        "min_gram":2,
                        "max_gram":15
                    }
                }
            }
        }
    }'; echo

    echo "analyze something with our shiny new analyzer"
    curl -XGET "localhost:9200/$INDEX_NAME/_analyze?analyzer=analyzer1&pretty=true" -d 'abcd'

    echo "remove the created index"
    curl -XDELETE "http://localhost:9200/$INDEX_NAME/"; echo

    echo "create new index again with mapping"
    curl -X PUT "http://localhost:9200/$INDEX_NAME/" -d '{
        "index":{
            "analysis":{
                "analyzer":{
                    "analyzer1":{
                        "type":"custom",
                        "tokenizer":"standard",
                        "filter":[ "standard", "lowercase", "stop", "kstem", "ngram" ]
                    }
                },
                "filter":{
                    "ngram":{
                        "type":"ngram",
                        "min_gram":2,
                        "max_gram":15
                    }
                }
            }
        },
        "mappings": {
            "product": {
                "properties": {
                    "title": {
                        "type": "string",
                        "search_analyzer" : "analyzer1",
                        "index_analyzer" : "analyzer1"
                    }
                }
            }
        }
    }'; echo

我认为您的问题是 analysis 设置需要嵌套在 JSON 中的 settings 节点中，而不是 index 节点中因为你有它。请引用Elasticsearch Create Index API有关构建 JSON 的详细信息。

因此，您的创建索引调用应如下所示:

curl -X PUT "http://localhost:9200/$INDEX_NAME/" -d '{
    "settings":{
        "analysis":{
            "analyzer":{
                "analyzer1":{
                    "type":"custom",
                    "tokenizer":"standard",
                    "filter":[ "standard", "lowercase", "stop", "kstem", "ngram" ]
                }
            },
            "filter":{
                "ngram":{
                    "type":"ngram",
                    "min_gram":2,
                    "max_gram":15
                }
            }
        }
    },
    "mappings": {
        "product": {
            "properties": {
                "title": {
                    "type": "string",
                    "search_analyzer" : "analyzer1",
                    "index_analyzer" : "analyzer1"
                }
            }
        }
    }
}';
