solrj - Is there a way to query Solr for a document with the most recent time field? -


if solr documents has 

<field name="timestamp" type="solr.triedatefield" indexed="true" stored="true"  required="true" multivalued="false"/>

how can query recent document?

only way i've discovered far sort descending date , limit rows 1 has limitations when want recent version of documents id 1,2,3,4

something similar get records highest/smallest <whatever> per group

i seem have gotten results im looking using solr group query

  group=true&group.field=groupid&group.sort=timestamp desc
