Elasticsearch index creation with mapping

Question

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

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.

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"
                }
            }
        }
    }
}';
