• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ly hang xa hoi. hieu ((ve cham) OR (vu cham)) ((tuc va) or (luc va)) hanh vi va triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ly hang xa hoi. hieu ((ve cham) OR (vu cham)) ((tuc va) OR (luc va)) hanh vi va triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ly hang xa hoi. hieu ((ve cham) OR (vu cham)) ((tuc va) or (luc va)) hanh vi va triet".
• Adding a wildcard symbol may retrieve word variants: tu sach ly hang xa hoi. hieu ((ve cham) OR (vu cham)) ((tuc va) or (luc va)) hanh vi va triet*.
