• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach ty) OR (sach thu)) nang x hoi. hieu ve cam luc va ((hanh vai) or (hanh tai)) cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ty) OR (sach thu)) nang x hoi. hieu ve cam luc va ((hanh vai) OR (hanh tai)) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ty) OR (sach thu)) nang x hoi. hieu ve cam luc va ((hanh vai) or (hanh tai)) cua te".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ty) OR (sach thu)) nang x hoi. hieu ve cam luc va ((hanh vai) or (hanh tai)) cua te*.
