autocomplete with search field options of a multiple field doesn't seem to work

I have a simple entityreference views created that I was hoping to use as the feed for an autocomplete entityreference.

That view have two fields, title and another textfield that is configured as multiple values in the entity I am referencing.

I was hoping to be able to search for either field but that's not working. Even more, if I select only the multiple feed nothing is being found.

I have tracked the issue down to entityreference/views/entityreference_plugin_display.inc:75 (7.x-1.0)

      // Build the condition using the selected search fields
      foreach ($style_options['search_fields'] as $field_alias) {
        if (!empty($field_alias)) {
          // Get the table and field names for the checked field
          $field = $this->view->query->fields[$this->view->field[$fild_alias]->field_alias];
          // Add an OR condition for the field
          $conditions->condition($field['table'] . '.' . $field['field'], $value, 'LIKE');
        }
      }

Apparently, the field_alias of this specific field is 'nid' while the real alias of the query in my case is 'field_data_field_nombre_field_nombre_value', this would be probably reproduceable by using any multiple feed and trying to use it for searching.

I was hoping to fix it, but as it seems that I need to dive deep into views core to see why this is happening I probably won't be able to do that right now, so hoping to get some help/advice on this.
