  Note that this view uses key arrays to enforce sorting, just to show you the possible variations. The disadvantage is that you can't use ''key="Scott"'' to search for Scotts groups, you need to use ''startkey=[''''''"Scott"]&endkey=["Scott",{}]''.
  
- Unlike the previous method, you can't use ''include_docs=true'' now to get all information about the contacts that are in a group or the groups that a contact has. The reason is that the original documents that were used in generating the view are not the contact or group documents, they are the relationship documents. If you want that information, you'll have to fetch it separately (you can use a POST view to ''/db/_alldocs'' to grab a bunch of documents in one go).

  If this is becoming a problem due to roundtrip times to the database, an acceptable solution is to duplicate the needed information in the relationship documents. You trade the inconvenience of maintaining multiple copies of the same data for the low access time to that data. Unless you have extreme requirements however, you do not need to do this.
