Hello, how would i make my program search for keywords in a textbox?


Example:

txtWrite => text box
lblReply => label

Code:
If txtWrite.text = "hello computer how are you?" then
lblReply.text = "I am fine thankyou for asking."
End if
In the above code there is a bit of a problem what if the user types
"hello how are you?" or "hi computer how are you" it wont work because it must be exact is there a way to do a keyword search inside the textbox.
Im not good at databases so unless you can explain how to retrieve and store information in one please dont you it ina reply.
