Thanks jhourcle, This is a common query. I used two ranges of same table because the range clause is exactly as 
AND ((UCSII.REC_STATUS = 'A'
AND UCSII.UCSIIU_RECEIPT_AT_MOT_DT between 
to_date(?,'mm/dd/yyyy') and to_date(?,'mm/dd/yyyy') ) 
-- <1.start date, 2.end date>
OR (UCSII.UCSIIU_RECEIPT_AT_MOT_DT between 
to_date(?,'mm/dd/yyyy') and to_date(?,'mm/dd/yyyy')  
-- <3.start date, 4.end date>
AND UCSII.REC_STATUS = 'I'
AND UCSII.UCSIIU_CIF_SENT_TO_ITA_CNT > 0))
