How do I access my iMessages through my gmail account?

[iMore Question]

I used to be able to search "SMS" search bar in my gmail account and see my entire text history, or search "SMS (insert name or phone number) to see just my text history with that person. I had'nt noticed that I can't do this any longer since switching from Android to Iphone. I now need to print out a specific text history for proof in legal proceedings, and as it is rather extensive (last year or so's worth) I am hoping to not have to just copy and paste each one on my phone...

Text messages can be extracted from the back-up file on a computer made via iTunes... Google or Bing search keywords "extract iPhone backup"
