How do I create search for multiple fields in dataset?

Thank you. It is so hard when you’re not sure what part relates to what. This is what I’ve changed it to so far (but still not working):

import wixData from “wix-data” ;

// For full API documentation, including code examples, visit Velo API Reference - Wix.com
export function dropdown1(event) {

//TODO: write your page related code here…

wixData.query( “therapies” )
.contains( ‘therapy’ , $w( ‘#dropdown1’ ).value)
.or(
wixData.query( “therapies” )
.contains( ‘therapyType2’ , $w( ‘#dropdown1’ ).value)
)
.or(
wixData.query( “therapies” )
.contains( ‘therapyType3’ , $w( ‘#dropdown1’ ).value)
)
.find()
.then(res => {
$w( ‘#repeater1’ )
});
}
