How to retrieve deleted texts from iPhone 5?

I deleted my texts but when I got to the left of my home screen (search) and enter words in the texts, they appear. When I click on it, it takes me to the text app but not the specific texts. How can I find these texts again?

Once something is deleted its gone for good. There must be.something wrong. With your phone.

Once you deleted your text it will be deleted unless you back it up before you delete.

The one your searching is just a history of that application but when you visit it its no longer there
the way the phone understands is that you search for it because you have to go to the app where you saw it I'm sorry.

Those deleted texts are still stored in iPhone database log files. So you can recover them with the 3rd party iPhone recovery tool. Such as http://www.datarecoveryforiphone.com/ios-data-recovery.html

If it works, can you give me the best answer?
