What can i do so that people can search for other peoples full name on my website like it does on facebook

my site is http://www.naijaping.com

The search does search for the Name or “Profile” Name of the User, including if they have a Space as sort of a “Last Name”

i dont know what happened because the search on both my real and test site didnt find the last name at all. all it found was just the name., it didnt find the Last name which is extra profile created , when you search for full name ut says sorry not found but when you search for just name it will find it. please what can i do.

regards
