• Performing a fuzzy search may retrieve terms with similar spellings: te sach ty ((hang ha) OR (hang hai)) hoi. hieu van lam xuc ((va danh) or (va hanh)) vai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty ((hang ha) OR (hang hai)) hoi. hieu van lam xuc ((va danh) OR (va hanh)) vai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty ((hang ha) OR (hang hai)) hoi. hieu van lam xuc ((va danh) or (va hanh)) vai cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach ty ((hang ha) OR (hang hai)) hoi. hieu van lam xuc ((va danh) or (va hanh)) vai cua tre*.
