公式の ElasticSearch クライアントに基づくmongoosasticを使用しています。Mongoosastic は、MongoDB で ElasticSearch を使用できるようにするプラグインです。私は次のような基本的なクエリを実行しました

NodesModel.search({
    "query_string": {
        "query": "developed"
    }
}, function(err, results) {
    console.log(err, JSON.stringify(results));
});

そして彼らはうまくいきます。ただし、現在、elasticsearch のステミング機能を有効にしようとしています。公式の ES ドキュメントのステミングの例を使用しましたが、mongoosastic では動作しません。私はもう試した

NodesModel.search({
    "query_string": {
        "query": "developed"
    },

    "index": {
        "analysis": {
            "analyzer": {
                "my_analyzer": {
                    "tokenizer": "standard",
                    "filter": ["standard", "lowercase", "my_stemmer"]
                }
            },
            "filter": {
                "my_stemmer": {
                    "type": "stemmer",
                    "name": "light_german"
                }
            }
        }
    }

}, function(err, results) {
    console.log(err, JSON.stringify(results));
});

出力は次のとおりです。

私が見るように、mongoosastic は次のように最初のパラメーターを ES nodejs クライアントに渡します。

schema.statics.search = function(query, options, cb){
    if (arguments.length === 2) {
      cb = arguments[1]
      options = {}
    }

    options.hydrateOptions = options.hydrateOptions || defaultHydrateOptions || {};

    if (query === null)
      query = undefined

    var model = this
      , esQuery = {
        body: {
          query: query
        },
        index: options.index || indexName,
        type:  options.type  || typeName
      }
     if (options.highlight) {
        esQuery.body.highlight = options.highlight;
     }
 .......

私の質問は、ステミングを機能させるにはどうすればよいですか?

別のプラグインの上にプラグインを使用することはお勧めしません。

また、imo elasticsearch はデータベースとして使用するのではなく、インデックス サービスのように使用する必要があります。

元の低レベル パッケージを試してみてください。習得が簡単で、問題なく動作します。
