弹性搜索索引创建与映射 [英] Elasticsearch index creation with mapping

问题描述

我正在努力创建索引的简单任务，目标是使用分析器和字段映射创建索引。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，并且找不到用于字段[$ field]]的分析器[analyzer1]，我创建一个脚本来显示问题：

I'm struggling with the simple task of index creation, the goal is to create an index with an analyzer and a field mapping. When I create a index with an analyzer i can talk to the analyzer via the analyze api calls, but when I add the mapping information the create index calls fails with "Analyzer [analyzer1] not found for field [$field]]", I created a script to show the problem:

    #!/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

推荐答案

我相信你的问题是分析设置需要嵌套在JSON中的设置节点中，而不在索引节点。请参阅弹性搜索创建索引API ，了解有关构建JSON。

I believe your issue is that the analysis settings need to be nested within a settings node in your JSON, not within an index node as you have it. Please reference the Elasticsearch Create Index API for details on constructing the JSON.

因此，您的创建索引调用应如下所示：

Therefore, your create index call should look like the the following:

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"
                }
            }
        }
    }
}';
