• Performing a fuzzy search may retrieve terms with similar spellings: te sach y nang ((o hai) OR (so hai)). ((hieu ve) or (hieu va)) cao suc van hanh than cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y nang ((o hai) OR (so hai)). ((hieu ve) OR (hieu va)) cao suc van hanh than cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y nang ((o hai) OR (so hai)). ((hieu ve) or (hieu va)) cao suc van hanh than cua tre*".
