I've got two ULs with IDs 'ul1' and 'ul2'.
JS:
function journalsearch() {
// Declare variables
var input, filter, ul, li, a, i, txtValue;
input = document.getElementById('myInput');
filter = input.value.toUpperCase();
ul = document.getElementById('ul1','ul2');
li = ul.getElementsByTagName('li');
// Loop through all list items, and hide those who don't match the search query
for (i = 0; i < li.length; i++) {
a = li.getElementsByTagName("a")[0];
txtValue = a.textContent || a.innerText;
if (txtValue.toUpperCase().indexOf(filter) &g
