• Performing a fuzzy search may retrieve terms with similar spellings: te sach ((ky tang) OR (kho tang)) ha hoi. hieu ((van cam) or (van nam)) xuc va danh vai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((ky tang) OR (kho tang)) ha hoi. hieu ((van cam) OR (van nam)) xuc va danh vai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((ky tang) OR (kho tang)) ha hoi. hieu ((van cam) or (van nam)) xuc va danh vai cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach ((ky tang) OR (kho tang)) ha hoi. hieu ((van cam) or (van nam)) xuc va danh vai cua tre*.
