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