• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach ky) or (sac ky)) tang ma hoi. hieu ve cac ((lo van) OR (vo van)) anh giau cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ky) OR (sac ky)) tang ma hoi. hieu ve cac ((lo van) OR (vo van)) anh giau cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) or (sac ky)) tang ma hoi. hieu ve cac ((lo van) OR (vo van)) anh giau cua tre".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ky) or (sac ky)) tang ma hoi. hieu ve cac ((lo van) OR (vo van)) anh giau cua tre*.
