Thanks Edward. As an experiment I was trying to write my own filter and use the scan.setFilter (..) method to set it. Is this even possible as I got into issues -- started giving some region server exception. Based on your response if the filtering is applied on the server side obviously my local custom filter class cannot be used. Am I guessing it right ??
