• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((thi thanh) OR (thi hong)) o hai. hieu van cac ((luc ban) OR (luc bat)) thanh de cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((thi thanh) or (thi hong)) o hai. hieu van cac ((luc ban) OR (luc bat)) thanh de cua te".
• Adding a wildcard symbol may retrieve word variants: te sach ((thi thanh) or (thi hong)) o hai. hieu van cac ((luc ban) OR (luc bat)) thanh de cua te*.
