• Performing a fuzzy search may retrieve terms with similar spellings: vu sach ly ((hang hai) or (hoang mai)) khoi. hieu ve cam xuc ((va danh) OR (va hanh)) vi cua viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ly ((hang hai) OR (hoang mai)) khoi. hieu ve cam xuc ((va danh) OR (va hanh)) vi cua viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ly ((hang hai) or (hoang mai)) khoi. hieu ve cam xuc ((va danh) OR (va hanh)) vi cua viet".
• Adding a wildcard symbol may retrieve word variants: vu sach ly ((hang hai) or (hoang mai)) khoi. hieu ve cam xuc ((va danh) OR (va hanh)) vi cua viet*.
