A simple dataset filtering

Hi,

I just tested this and it should work, just change it accordingly to filter a dataset

wixData.query("myCollection")
  .eq("a", "b")
  .eq("c", "d")
  .eq("e", "f")
  .or(
    wixData.query("myCollection")
       .eq("a", "b")
       .eq("c", "d") 
       .isEmpty("e")
  )
  .find()
  .then( (results) => {
      //do cool stuff here
  });

[UPDATED] For filtering dataset (tested)

export function button1_click(event) {
    $w("#dataset1").setFilter( wixData.filter()
        .eq("a", "b")
        .eq("c", "d")
        .eq("e", "f")
        .or(
            wixData.filter()
            .eq("a", "b")
            .eq("c", "d") 
            .isEmpty("e")
        )
    )
    .then( () => {
        console.log('Done');
    });
}
