When logged into Gmail and using Chat, if I have a coworker named Bob Example and I started typing Bob in the search in the lower left for chat (or type Bob and click the magnifying glass,) Bob Example appears as a contact to chat with. Now there are no results.
If I start typing Bob's email address, he appears as a result to start a chat with.
It also seems that Bob will show up if he was a recently contacted chat connection.
If I go into Gmail settings, the menu for Chat shows only Chat: On/Off, so I suspect it's using Hangouts chat (in Chrome) rather than the old Gchat because before there were several settings in that menu, not just on/off.
How do I get Hangouts Chat to use the company directory to find people in Chat, rather than just recent contacts?
