How to add multiple conditions in filter?

Hello! I am looking for a solution to combine the two filters below: (displaying the items that fulfill both conditions)

$w(“#dataset1”).setFilter(wixData.filter().contains(“aaa”,$w(“#dropdown1”).value))
$w(“#dataset1”).setFilter(wixData.filter().contains(“bbb”,$w(“#dropdown2”).value))

I have tried this below, but it doesn’t work.
$w(“#dataset1”).setFilter(wixData.filter().contains((“aaa,$w(”#dropdown1").value) && (“bbb”,$w(“#dropdown2”).value)))

The way to combine 2 or more clauses as seen in the documentation is as follows:

$w("#myDataset").setFilter(wixData.filter()
    .startsWith("lastName", "D")
    .ge("age", "21") 
);

In your case, replace these clauses with yours - contains(…).
