• Performing a fuzzy search may retrieve terms with similar spellings: thu dac khoa ((tang ha) or (lang ha)) noi. chieu tu cham ((xuc van) OR (luc van)) thanh ve cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu dac khoa ((tang ha) OR (lang ha)) noi. chieu tu cham ((xuc van) OR (luc van)) thanh ve cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu dac khoa ((tang ha) or (lang ha)) noi. chieu tu cham ((xuc van) OR (luc van)) thanh ve cua tre".
• Adding a wildcard symbol may retrieve word variants: thu dac khoa ((tang ha) or (lang ha)) noi. chieu tu cham ((xuc van) OR (luc van)) thanh ve cua tre*.
