Search bar againest multiple database fields

Hi,
Thanks for taking time to read this. I am trying to create a search bar that can search either tutor name or course name. what I can think about is create an if, else statment to run different searching code. However the code doesn’t work. Can anyone help me with this problem thanks.

import wixData from ‘wix-data’;
$w.onReady( function () {
//TODO: write your page related code here…

});

export function input2_keyPress(event) {
let SearchValue = $w(“#input2”).value;
if ($w(‘#dataset1’).setFilter(wixData.filter().contains(“courseName” ,SearchValue))){

}//.or(wixData.filter().contains('tutorFname', SearchValue1)) 

else if ($w(‘#dataset1’).setFilter(wixData.filter().contains(‘tutorFname’ ,SearchValue))){

} 

}
