Hi!
Make sure to have the search in pages option acitvated in this case: https://goo.gl/oPkRiQ
If you mean re-directing to the first result, then you can configure that on the General Options -> Behavior page: https://goo.gl/eEh0FX
If you want to add additional keywords, I suggest creating a custom field on the page editor, and then selecting that custom field on the search options to search for: https://goo.gl/g3phyo
