keyword filtering

Hi all,
I'm quite newbie for VBA for excel, my friend asked me a favor to filter the data on his excel, so when he enter some keyword, the table would sorted (only show the row that have that keyword), and if possible that he enter it few keyword.

keyword example VB, oracle

table example

project description
school making oracle dtbase
<blank> VB project
java database

when he enter vb, oracle then the table become

project description
school making oracle dtbase
<blank> VB project

any idea how? or someone would mind to give me example/make what the macro would like?
since i never use VB before it really difficult for me to built it from scratch..

thanks for your help
