sorting on a multivalued field
I'd like to be able to sort documents based on date. For ascending sort, the first date in the future relative to the time of the search would be used as the sort date. If all dates are in the past, the last date should be used. For descending sort, the opposite . . . document 1: id: 1 date: 2008-03-10 11am, 2008-03-10 3pm, 2008-04-10 11am document 2: id: 2 date: 2008-02-10 12pm, 2008-03-10 1pm, 2008-03-11 12pm, 2008-03-11 1pm, 2008-04-02 12pm at 11:30am on 2008-03-10, doc2 sort before doc1 in an ascending sort and at 1:30pm, doc1 would sort before doc2 It appears that adding sort functions would be done in Lucene, and not in solr.
