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