+
+```javascript

+    .thenEvaluate(function() {
+        document.querySelector('input[name="q"]').setAttribute('value', '%term%');
+        document.querySelector('form[name="f"]').submit();
+    }, {
+        term: 'CasperJS'
+    })
+    .then(function(self) {
+        // Click on 1st result link
+        if (self.click('h3.r a')) {
