• Performing a fuzzy search may retrieve terms with similar spellings: te sach ty lang xa hoi. hieu van luat duoc va ((((thanh ve) OR (thanh va))) or (hanh va)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty lang xa hoi. hieu van luat duoc va ((((thanh ve) OR (thanh va))) OR (hanh va)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty lang xa hoi. hieu van luat duoc va ((((thanh ve) OR (thanh va))) or (hanh va)) cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach ty lang xa hoi. hieu van luat duoc va ((((thanh ve) OR (thanh va))) or (hanh va)) cua tre*.
