• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky trang ha hoi. ((hieu van) or (lieu va)) lam duc ban ((thanh di) OR (thanh doi)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky trang ha hoi. ((hieu van) OR (lieu va)) lam duc ban ((thanh di) OR (thanh doi)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky trang ha hoi. ((hieu van) or (lieu va)) lam duc ban ((thanh di) OR (thanh doi)) cua tre".
• Adding a wildcard symbol may retrieve word variants: tu sac ky trang ha hoi. ((hieu van) or (lieu va)) lam duc ban ((thanh di) OR (thanh doi)) cua tre*.
