• Performing a fuzzy search may retrieve terms with similar spellings: thu ((sach ty) OR (sach tu)) nang co hoi. lieu va chat xuc ((va hanh) or (va tinh)) vi luu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sach ty) OR (sach tu)) nang co hoi. lieu va chat xuc ((va hanh) OR (va tinh)) vi luu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sach ty) OR (sach tu)) nang co hoi. lieu va chat xuc ((va hanh) or (va tinh)) vi luu tre".
• Adding a wildcard symbol may retrieve word variants: thu ((sach ty) OR (sach tu)) nang co hoi. lieu va chat xuc ((va hanh) or (va tinh)) vi luu tre*.
