+**Warning:** Type deletion is an *asynchronous operation*, that keeps going after the `deleteType` method has returned `true`. If you try to perform `addItem`, `deleteItem`, `updateItem` or `updateItems` right after a `deleteType` operation, chances are you get an `IndexingInProgress` exception, because those ops aren't allowed while the `deleteType` is still in progress. If that happens, just wait a little and try again.
+
+```php
+$mySearchEngine->deleteType('estudio'); // async op
+$new_types = $mySearchEngine->addType('estudio'); // ok
+$notReadyYet = true;
+while($notReadyYet){
+  try{
+    $mySearchEngine->addItem('estudio', 'AAA', $someItem); // it may not be ready yet!!
+    $notReadyYet = false;
+  } catch (IndexingInProgress $ipe) {
+    sleep(3); // just wait a little
