You cannot search Gmail accounts easily. There is no list of people who are on Gmail. This list would hurt the privacy of the owners.
The list of groups on Gmail is not public. The groups are created by individuals. They might contain some private information as well.
You could find you Gmail contacts on the left. There is a list of Gmail contacts on the left pane. These contacts are the one who can be chatted with.
