En castellano
Necesito que no se haga la busqueda sobre el optgroup, sino solo sobre los options


Use a custom matcher. As the user types their search term, Select2 passes the search term and each top-level item (an <option> or <optgroup>) to your custom matcher function.

The example code here is almost exactly what you need. The only difference is that you will also need to check for a match if the data item does not contain a children property. (In the example, they are only interested in matching <optgroup> children, so they always return null for top-level <option>s. You will want to match against those items as well as children of <optgroup>s.)
