Question

是否有一种优雅的方式可以通过编程方式获取ElasticSearch 5.3或5.4的所有分析器？我已经使用了一些带有Java驱动程序的Java代码，但这不是一个干净的解决方案：

public Map<String, AnalyzerProvider<?>> extractAllIndices() throws IOException {
    Settings settings = Settings.builder()
            .put(Environment.PATH_HOME_SETTING.getKey(), System.getProperty("user.home"))
            .put(IndexMetaData.SETTING_VERSION_CREATED, 1)
            .put(IndexMetaData.SETTING_VERSION_CREATED_STRING, "1")
            .put(IndexMetaData.SETTING_NUMBER_OF_SHARDS, 1)
            .put(IndexMetaData.SETTING_NUMBER_OF_REPLICAS, 1)
            .build();
    Environment environment = new Environment(settings);
    AnalysisModule module = new AnalysisModule(environment, Collections.emptyList());
    IndexSettings indexSettings = new IndexSettings(new IndexMetaData.Builder("test")
            .settings(settings)
            .build(),
            settings);
    return module.getAnalysisRegistry().buildAnalyzerFactories(indexSettings);
}

此代码检索驱动程序内部使用的所有分析程序。但这相当糟糕。

这些是我使用上面的代码在5.3驱动程序中找到的所有分析器：
