->andWhere('filed LIKE :name:')
->getQuery()
->exequte(array('name' => $value));
use any sql you want, just place named parameters and then pass to exequte call array with keys as named parameters without : at start and end. So if you write
->where('xxx = :randomvar:')
->andWhere('filed LIKE :anotherrandomvar:')
then to exequte you pass it like this
->exequte(array('randomvar' => $value1, 'anotherrandomvar' => $value2));
