How to search multiple columns in javascript

function myFunction() {

// Declare variables 
var input = document.getElementById("myInput");
var filter = input.value.toUpperCase();
var table = document.getElementById("myTable");
var trs = table.tBodies[0].getElementsByTagName("tr");

// Loop through first tbody's rows
for (var i = 0; i < trs.length; i++) {

  // define the row's cells
  var tds = trs[i].getElementsByTagName("td");

  // hide the row
  trs[i].style.display = "none";

  // loop through row cells
  for (var i2 = 0; i2 < tds.length; i2++) {

    // if there's a match
    if (tds[i2].innerHTML.toUpperCase().indexOf(filter) > -1) {

      // show the row
      trs[i].style.display = "";

      // skip to the next row
      continue;

    }
  }
}
