使用自定義設置的ElasticSearch高級API創建索引返回錯誤

Question

我試圖創建一個自定義設置廣告指數作為解釋在這里 。 我正在使用ElasticSearch 6.3

這是我的代碼：

public CreateIndexResponse createIndex(@NotNull String indexName) throws IOException {
        CreateIndexRequest request = new CreateIndexRequest();
        request.index(indexName);
        Settings.Builder settingsBuilder =
                Settings.builder()
                        .put("settings.analysis.filter.autocomplete_filter.type", "edge_ngram")
                        .put("settings.analysis.filter.autocomplete_filter.min_gram", "1")
                        .put("settings.analysis.filter.autocomplete_filter.max_gram", "10")
                        .put("settings.analysis.analyzer.autocomplete.type", "custom")
                        .put("settings.analysis.analyzer.autocomplete.tokenizer", "standard")
                        .putList("settings.analysis.analyzer.autocomplete.filter", "lowercase", "autocomplete_filter");
        request.settings(settingsBuilder);
        return elasticSearchClient.indices().create(request, RequestOptions.DEFAULT);
    }

我有這個例外：

ElasticsearchStatusException [Elasticsearch異常[type = illegal_argument_exception，原因=未知設置[index.settings.analysis.analyzer.autocomplete.filter]請檢查是否已安裝任何必需的插件，或檢查重大更改文檔以了解已刪除的設置]]

我正在使用AWS ElasticSearch實例。 我更喜歡使用構建器而不是普通的JSON來創建我的設置請求。 難道我做錯了什么？

我發現了問題。 似乎鍵不能包含settings前綴。

工作代碼如下：

public CreateIndexResponse createIndex(@NotNull String indexName) throws IOException {
    CreateIndexRequest request = new CreateIndexRequest();
    request.index(indexName);
    Settings.Builder settingsBuilder =
            Settings.builder()
                    .put("analysis.filter.autocomplete_filter.type", "edge_ngram")
                    .put("analysis.filter.autocomplete_filter.min_gram", "1")
                    .put("analysis.filter.autocomplete_filter.max_gram", "10")
                    .put("analysis.analyzer.autocomplete.type", "custom")
                    .put("analysis.analyzer.autocomplete.tokenizer", "standard")
                    .putList("analysis.analyzer.autocomplete.filter", "lowercase", "autocomplete_filter");
    request.settings(settingsBuilder);
    return elasticSearchClient.indices().create(request, RequestOptions.DEFAULT);
}
