• Performing a fuzzy search may retrieve terms with similar spellings: ((thuoc sach) OR (hoc sach)) tu lenh van hoi. thi van nam xuc va dinh ((thi duc) or (thi dua)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((thuoc sach) OR (hoc sach)) tu lenh van hoi. thi van nam xuc va dinh ((thi duc) OR (thi dua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thuoc sach) OR (hoc sach)) tu lenh van hoi. thi van nam xuc va dinh ((thi duc) or (thi dua)) tre".
• Adding a wildcard symbol may retrieve word variants: ((thuoc sach) OR (hoc sach)) tu lenh van hoi. thi van nam xuc va dinh ((thi duc) or (thi dua)) tre*.
