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