• Performing a fuzzy search may retrieve terms with similar spellings: te sach lo nang xa hoi. ((hieu van) or (lieu va)) ((cau duc) OR (cau luc)) va danh di cau tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach lo nang xa hoi. ((hieu van) OR (lieu va)) ((cau duc) OR (cau luc)) va danh di cau tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach lo nang xa hoi. ((hieu van) or (lieu va)) ((cau duc) OR (cau luc)) va danh di cau tre".
• Adding a wildcard symbol may retrieve word variants: te sach lo nang xa hoi. ((hieu van) or (lieu va)) ((cau duc) OR (cau luc)) va danh di cau tre*.
