An idea for multiple collection search

I have found a way to search multiple collections.  It will do until Logos implements a quicker way to search more than 1 collection.

I have created a Collection called "#Collection Search".  I included the hash mark so it will show up at the top of the collections list in collections window and search window.  I created a shortcut to this collection. 

When I want to do a search on more than one collection I initiate the search as usual then click on the "#Collection Search" shortcut and then just add/delete entries to/from the "+ Plus these resources" area.  I then select the "#Collection Search" collection in the search dialogue and it searches whatever collections I have set up.  Hope this idea helps someone else!
