• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach uu) or (sach thu)) sang tao hoi. thien van cam loc ((va hanh) OR (va thanh)) gian xu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach uu) OR (sach thu)) sang tao hoi. thien van cam loc ((va hanh) OR (va thanh)) gian xu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach uu) or (sach thu)) sang tao hoi. thien van cam loc ((va hanh) OR (va thanh)) gian xu tre".
• Adding a wildcard symbol may retrieve word variants: tu ((sach uu) or (sach thu)) sang tao hoi. thien van cam loc ((va hanh) OR (va thanh)) gian xu tre*.
