Description

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:

<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>

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:

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.
  }
}
