Multilingual search bar

HellošŸ˜‰!
I have a multilingual website. I was having trouble letting my search bar search in other languages. I made a search bar to search for my dataset. I made a field for the Japanese search value in my database. I added it to my code. But the search bar doesn’t let me search for the Japanese name.

 import wixData from 'wix-data';

$w.onReady( function() {

})
export function input1_keyPress(event, $w) {
 let searchValue = $w("#input1").value;
    $w("#dataset1").setFilter(wixData.filter().contains('name', searchValue)
    .or(wixData.filter().contains('title', searchValue)))
    .or(wixData.filter().contains('japanese', searchValue));
}

The value ā€˜name’ is the name of the image. The value ā€˜title’ is the name of the author. And ā€˜japanese’ is the value in the database for the Japanese name of the image.
The search bar works when I search in English. Does anyone know why? Did I forget some code? Also, is it possible to only show only the images with the tag ā€œpublishedā€ because I am letting people upload there own images and I would like to verify them before they are on the live site .
Regards
Arthur
