If document URL indexOf

I have some search page link: www.example.com/search.php?search=search_word, I am tried to make a default search URL. If people only type www.example.com/search.php via the browser, make a default URL as www.example.com/search.php?search=aaa. My code does not work.

<script src="../jquery.js"></script>
<script>
jQuery(document).ready(function(){
var currneturl = document.URL;
if(!document.URL.indexOf('?')){
    document.URL = currneturl + '?search=aaa';
}
});
</script>

The .indexOf() method returns -1 if the string is not found, and -1 is a truthy value such that !-1 is false. You need to explicitly test for -1:

if (document.URL.indexOf('?') === -1) {
