I think it would be easier for everyone if we were able to type in part of someone's name or clan and it would show up in the search. Some people and clans are long and if you don't type it in exactly as they spelled it in the search it won't show up. There are some people I can't find because they have all these special characters in their name. I know their name but can't remember their special characters in their name.
Could be helpful They have a similar feature in chat with @. They could probably incorporate something similar for the search bar.
