• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky ((nang xa) or (nang ma)) hoi. hieu ve cham xuc van ((minh va) OR (tinh va)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky ((nang xa) OR (nang ma)) hoi. hieu ve cham xuc van ((minh va) OR (tinh va)) cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky ((nang xa) or (nang ma)) hoi. hieu ve cham xuc van ((minh va) OR (tinh va)) cua tre*".
