Search (filter and sort) for related field in gridview is base an a series of action.. you can find some sample in this doc
http://www.yiiframework.com/wiki/653/displaying-sorting-and-filtering-model-relations-on-a-gridview/
in brief..
- In your model define your active relation in (main/pivot) model and add the getter for related field
- In your modelSearch in your dataProvider add the var fo related field, set the proper sort for sorting by new related field, add the relation in search function and adding proper filter in modelSearch condition
- Add the new attribute to the gridview..
Take a deep look to the scenario 2 in the link provided.. and you can find what you need
