• Performing a fuzzy search may retrieve terms with similar spellings: te sach y ((nang xa) or (lang xa)) hoi. hieu van chon luc va hanh ((di va) OR (dai va)) triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y ((nang xa) OR (lang xa)) hoi. hieu van chon luc va hanh ((di va) OR (dai va)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y ((nang xa) or (lang xa)) hoi. hieu van chon luc va hanh ((di va) OR (dai va)) triet".
• Adding a wildcard symbol may retrieve word variants: te sach y ((nang xa) or (lang xa)) hoi. hieu van chon luc va hanh ((di va) OR (dai va)) triet*.
