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