I'm not entirely convinced that the search function within Messages is working properly. I'm searching by the user's name, but it seems to be case-sensitive? Also, with the correct case sensitivity, not all of the messages are showing up that were sent by said user.
You are searching for the username, which I assume may not be in the text of the messages?
My guess it may not search for the username and only looks for the text. I will find out. If the search scenario is different, please PM me for what you are looking for. I will have the administrator look into it.
