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