This is correct: " I index it and feed it the timestamp at index time". You can sort desc on that field (can be a TrieDateField)

Is this something I have to do at index time or search time? Is the trick to have a field that holds the committed timestamp and boost on that field during search? If so, is this field something I can configure in Solr's schema.xml or must I index it and feed it the timestamp at index time? If I'm on the right track, does this mean I have to always append this field base boost to each query a user issues? If there is a wiki or article written on this topic, that would be a good start. In case it matters, I'm using Solr 5.2 and my searches are utilizing edismax. Thanks in advanced! Steve
