To delay the call to your server, use the following code in your onQueryTextChange method, the variables mQueryString and mHandler must be class variables. also check mHandler!=null

@Override
public boolean onQueryTextChange(String searchTerm) {
    mQueryString = searchTerm;
    mHandler.removeCallbacksAndMessages(null);

    mHandler.postDelayed(new Runnable() {
        @Override
        public void run() {
           //Put your call to the server here (with mQueryString)
        }
    }, 300);
    return true;
}
