• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach ty) OR (sach y)) anh mai hoi. hieu ve cam xuc va ((hanh vai) or (hanh va)) cu tren~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ty) OR (sach y)) anh mai hoi. hieu ve cam xuc va ((hanh vai) OR (hanh va)) cu tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ty) OR (sach y)) anh mai hoi. hieu ve cam xuc va ((hanh vai) or (hanh va)) cu tren".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ty) OR (sach y)) anh mai hoi. hieu ve cam xuc va ((hanh vai) or (hanh va)) cu tren*.
