Search for chat history from all your friends instead of just one

Sometimes, okay no, almost ALL the time I will tell a friend something or send them something but then forgot who I told it to a few months later but then really need to know who I told it to. It would be nice if I could type in a few words like you do when searching for a message for a singular person, except an option for your entire friends list (or possibly all the dms you have with people in all the groups that you are in) to find a message I sent to someone but have forgotten who they are or what the message was.
