Hello Liz Cooper,
Have you tried the "exact match" check box?
Searching with a space seems to be working for me. However I feel like I've run into this before. I also reinstalled today and I am using version 22.214.171.124. Not sure if maybe they've recently made any changes.
Let me know if you find the solution to your problem.
Thanks for your forum post!
Let's take this case off the forums and work on this offline, as it seems that we will need to do some investigation as to why this is occurring. I will be replying to you through the portal system.
