• Performing a fuzzy search may retrieve terms with similar spellings: vu sach ty ((nang xa) OR (lang xa)) hoi. lieu va chai cuc ((va thanh) or (ban thanh)) vi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ty ((nang xa) OR (lang xa)) hoi. lieu va chai cuc ((va thanh) OR (ban thanh)) vi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ty ((nang xa) OR (lang xa)) hoi. lieu va chai cuc ((va thanh) or (ban thanh)) vi cua tre".
• Adding a wildcard symbol may retrieve word variants: vu sach ty ((nang xa) OR (lang xa)) hoi. lieu va chai cuc ((va thanh) or (ban thanh)) vi cua tre*.
