• Performing a fuzzy search may retrieve terms with similar spellings: ((vu sach) OR (su sach)) nham nang mai hoi. hieu ve ((cam xuc) or (pham duc)) gia thanh ve cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu sach) OR (su sach)) nham nang mai hoi. hieu ve ((cam xuc) OR (pham duc)) gia thanh ve cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vu sach) OR (su sach)) nham nang mai hoi. hieu ve ((cam xuc) or (pham duc)) gia thanh ve cua tre".
• Adding a wildcard symbol may retrieve word variants: ((vu sach) OR (su sach)) nham nang mai hoi. hieu ve ((cam xuc) or (pham duc)) gia thanh ve cua tre*.
