• Performing a fuzzy search may retrieve terms with similar spellings: vu sach ky lang xa hoi. hieu va ((cac xuc) OR (chat xuc)) va dan vi ((cua tu) or (cua cu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ky lang xa hoi. hieu va ((cac xuc) OR (chat xuc)) va dan vi ((cua tu) OR (cua cu))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ky lang xa hoi. hieu va ((cac xuc) OR (chat xuc)) va dan vi ((cua tu) or (cua cu))*".
