how to filter the basicfilteredlist based upon the sign(+ve or -ve) of value.

I have created one autocompletecompletefield, and i added one basicfilteredlist to that. I have added one Dataset to the basicfilteredlist of type integer. My Dataset has contain both negative and positive integer values. When i enter any positive value in autocompletefield, i got both negative values and positive values.Now My requirement is " when i type the "-(Minus)", i want to get the only negative values. when i type positive value i want to get only positive values which starts with with the number which i have entered in autocompletefield".

Here is my code. 



basicfilteredlist.addDataSet(1,chs2,"Pressure",BasicFilteredList.SORT_BY_SECONDARY_FIELD); AutoCompleteField. acf1 = new AutoCompleteField(bfl1,Field.FIELD_LEFT){  
     public int getPreferredWidth() {
      return 70;
     public int getPreferredHeight() {
      return 30;
   protected void sublayout( int maxWidth, int maxHeight ){


Please help me ASAP.
