• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sac ky) or (cac ky)) lang ha hoi. hieu va cap nuoc tuan ((anh dai) OR (anh bai)) sua chua~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sac ky) OR (cac ky)) lang ha hoi. hieu va cap nuoc tuan ((anh dai) OR (anh bai)) sua chua*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sac ky) or (cac ky)) lang ha hoi. hieu va cap nuoc tuan ((anh dai) OR (anh bai)) sua chua*".
