Thanks, I solved this problem. I found that if what i typed is lowercase, the result is not case senstive, e.g. if search for "database" it would return "DATABASE", "database". However, if what i typed is uppercase, the result is case sensitive, e.g. if search for "DATABASE", no results would return. So I just transfer the input to lowercae using toLower(), and it works. Is there anyting wrong with this?
