Commonly used contacts on top when texting or emailing?

Hi all... I searched for this with no luck... is there a way to get Iphone to show me contacts in the list as a type a name based on any semblance of frequency of use? Example:

my wifes name is krista

when I want to text, I have to type her whole name in, get past all the kristens kristophers etc.. before I can see her... even though I literally have never texted that person. Gmail's web interface does this flawlessly... any way to get it to show commonly used ones above random contacts...?

thanks in advance! C
