• Performing a fuzzy search may retrieve terms with similar spellings: te sac ky lang xa hoi. ((lieu va) or (hieu qua)) ((tham nuoc) OR (thoat nuoc)) va danh vi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky lang xa hoi. ((lieu va) OR (hieu qua)) ((tham nuoc) OR (thoat nuoc)) va danh vi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky lang xa hoi. ((lieu va) or (hieu qua)) ((tham nuoc) OR (thoat nuoc)) va danh vi cua tre".
• Adding a wildcard symbol may retrieve word variants: te sac ky lang xa hoi. ((lieu va) or (hieu qua)) ((tham nuoc) OR (thoat nuoc)) va danh vi cua tre*.
