CMR collection search has recently been changed to respect all temporal ranges in the collection. Previously, if you had two temporal ranges in your collection of 1/1/2017-2/1/207 and 5/1/2017-6/1/2017, the collection would show up in a temporal search for 4/1/2017-4/3/2017, despite the gap in temporal ranges. Now, the collection will no longer show up in that search. The collection will show up in a temporal search within either range. Granule search is unaffected by this change.
This change is currently in the UAT environment and will move to production on 7/26/17.
