ElasticSearch高级API使用自定义设置创建索引返回错误

我正试图用自定义设置创建广告索引,如前所述 here . 我用的是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);
    }

但我有个例外:

ElasticSearchStatusException[ElasticSearch异常 [类型=非法参数异常,原因=未知设置 [index.settings.analysis.analyzer.autocomplete.filter]请检查是否安装了任何必需的插件,或检查是否发生了中断更改删除设置的文档]]

我正在使用一个aws弹性搜索实例。我更喜欢使用构建器而不是简单的json来创建我的设置请求。我做错什么了吗?

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); }
