Kevin Risden commented on SOLR-9666:
------------------------------------
Since it seems like you are just looking for schema information, maybe the
schema api would be useful?

> Extract dynamic fields in LukeResponse

> Project: Solr
> Issue Type: Improvement

> LukeRequestHandler (/admin/luke), when invoked with the show=schema
> parameter, returns a list static fields and dynamic fields.
> For instance on my local machine
> http://localhost:8983/solr/collection1/admin/luke?show=schema returns
> something like this:
> {code:xml}
> <response>
> ...
> <lst name="schema">
> <lst name="fields">
> <lst name="foo">
> <str name="type">string</str>
> <str name="flags">I-S-----OF-----l</str>
> </lst>
> ...
> </lst>
> <lst name="dynamicFields">
> <lst name="bar_*">
> <str name="type">string</str>
> <str name="flags">I-------OF------</str>
> </lst>
> ...
> </lst>
> </lst>
> ...
> </response>
> {code}
> However, when processing a LukeRequest in SolrJ, only static fields are
> parsed and made available to the client application through
> lukeResponse.getFieldInfo(). There does not seem to be a way for the client
> application to get the dynamic fields.
> Maybe we could parse dynamic fields and make them accessible ? Possibly
> something like this:
> {code}
> public class MyClass {
> public static void main(String[] args) throws Exception {
> SolrClient client = new
> HttpSolrClient("http://localhost:8983/solr/collection1";);
> LukeRequest request = new LukeRequest();
> request.setShowSchema(true);
> LukeResponse response = request.process(client);
> Map<String, FieldInfo> staticFields = response.getFieldInfo(); // SolrJ
> already provides this.
> Map<String, FieldInfo> dynamicFields = response.getDynamicFieldInfo(); //
> Proposed improvement.
> }
> }
> {code}
