Today the integration for this feature is not complete. It's not possible to search every document available in G Drive. It should be like this :
+1 Inability to search my files and to find files owned by others was one of the first things I noticed when testing the software. Not a deal breaker, but with 1000's of files generated by dozens of people search and other owners are a very frequent need when attaching files. Thanks!
This is in fact very necessary.
Google drive files are seldom stored in the "Root" and without being to search for potentially large numbers of files this great and necessary Google Drive file attach feature is rendered almost useless I'm afraid.
Here's hoping to see it in the future soon.
You won't be notified about changes to this idea.
