java - ElasticSearch 高级 API 使用自定义设置创建索引返回错误

Question

我正在尝试使用自定义设置创建广告索引，如所述 here 。我正在使用 ElasticSearch 6.3

这是我的代码:

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);
    }

但我有这个异常(exception):

ElasticsearchStatusException[Elasticsearch exception [type=illegal_argument_exception, reason=unknown setting [index.settings.analysis.analyzer.autocomplete.filter] please check that any required plugins are installed, or check the breaking changes documentation for removed settings]]

我正在使用 AWS ElasticSearch 实例。我更喜欢使用构建器而不是纯 JSON 来创建我的设置请求。我做错了什么吗？

我发现了问题。看来按键不能包含 settings 前缀。

工作代码是这样的:

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);
}
