• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) or (te sach)) y nang mai hoi. hieu va ((cac xuc) OR (chat xuc)) va dan ca cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (te sach)) y nang mai hoi. hieu va ((cac xuc) OR (chat xuc)) va dan ca cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (te sach)) y nang mai hoi. hieu va ((cac xuc) OR (chat xuc)) va dan ca cua tre".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (te sach)) y nang mai hoi. hieu va ((cac xuc) OR (chat xuc)) va dan ca cua tre*.
