Searching multiple columns in a database

I am a beginner at coding and have learned a lot from this forum. Hope you can help me with this:

I would like to search multiple columns in a database. I have found this link , but it only explains how to search one column.

This is my current code:

import wixData from "wix-data"; 

let debounceTimer; 

export function SearchBox_keyPress(event, $w)

 { if (debounceTimer) { clearTimeout(debounceTimer); debounceTimer = undefined; } 
 
debounceTimer = setTimeout(() => {
  
  filter($w('#SearchBox').value, ); }, 500); } function filter(title) { 
  $w('#dataset1').setFilter(wixData.filter().contains('title', title)) }

All help is appreciated.

Thank you very much.

Hi,
You can learn how to create collection data search functionality here .
This tutorial helps to create a search that checks all columns and you can get the needed one in the results.

Hello thanks for trying to help!

the link you suggested talks about displaying the results in a table. I would like to display my results in a repeater.The repeater would be the same one that displays the entire database collection. You can see my current search here: https://www.pandemicity.org/clinical-research

Thank you.
