What are the potential pitfalls of using keyup event for live search functionality in PHP?

Using the keyup event for live search functionality in PHP can lead to excessive server requests and slow down the performance of the application. To solve this issue, you can implement a delay before sending the search query to the server to reduce the number of requests being made. 

<input type="text" id="search" onkeyup="delaySearch()">

<script>
let delayTimer;
function delaySearch() {
    clearTimeout(delayTimer);
    delayTimer = setTimeout(sendSearchQuery, 500);
}

function sendSearchQuery() {
    let searchValue = document.getElementById('search').value;
    
    // Send AJAX request to server with searchValue
}
</script>
