Hi Sir @AV digital
Thanks for your response 
. i try to match the field and id but i get this error at this part. But how to make the result show in box?
let filter;
export function filter() {
filter = wixData.filter();
if ($w(‘#ifullname’).value !== undefined && $w(‘#ifullname’).value !== null && $w(‘#ifullname’).value !== “”) {
filter = filter.contains(“ifullname”, $w(‘#ifullname’).value);
}
if ($w(‘#icompetent’).value !== undefined && $w(‘#icompetent’).value !== null && $w(‘#icompetent’).value !== “”) {
filter = filter.contains(“icompetent”, $w(‘#icompetent’).value);
}
if ($w(‘#ilocation’).value !== undefined && $w(‘#ilocation’).value !== null && $w(‘#ilocation’).value !== “”) {
filter = filter.contains(“ilocation”, $w(‘#ilocation’).value);
}
$w("#dataset1").setFilter(filter);
