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