**Versions** (relevant - OpenSearch/): OpenSearch 2.13.0

**Describe the issue** :

We are using HLRC and extending the search capabilities at runtime with our custom search plugin with something like this

```auto
List<SearchPlugin> customPlugins = new ArrayList<>();
customPlugins.add(new myCustomPlugin());
SearchModule searchModule = new SearchModule(Settings.EMPTY, customPlugins);

SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
 XContentParser parser = JsonXContent.jsonXContent.createParser(new NamedXContentRegistry(searchModule.getNamedXContents()
searchSourceBuilder.parseXContent(parser);

```

we want to migrate from hlrc to java client, is there support for custom plugin/parser for java client? the java client doesnt seem to support .parsexContent, namedxContent, searchsourcebuilder  
**Configuration** :
