• Performing a fuzzy search may retrieve terms with similar spellings: vu sach ky ((nang xa) or (nang x)) hoi. thieu nien ((sach nuoc) OR (cac nuoc)) va hanh di cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ky ((nang xa) OR (nang x)) hoi. thieu nien ((sach nuoc) OR (cac nuoc)) va hanh di cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ky ((nang xa) or (nang x)) hoi. thieu nien ((sach nuoc) OR (cac nuoc)) va hanh di cua te*".
