Last change on this file since 30958 was 30958, checked in by kjdon, 8 years ago

in DocumentMetadataRetrieve, this was creating a paramlist with metadata=Title as the only parameter./Greenstone-3.08-candidate-2016.10.25-linux-x64 we need to use the param list from the original request so that we can get all metadata that is asked for.

41These two services will requery the MR for search results/document metadata based on collections or documents listed.
