• Performing a fuzzy search may retrieve terms with similar spellings: te ((sach thi) or (sach xa)) nang xa hoi. hieu van nam cuc ban ((thanh di) OR (thanh do)) cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach thi) OR (sach xa)) nang xa hoi. hieu van nam cuc ban ((thanh di) OR (thanh do)) cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach thi) or (sach xa)) nang xa hoi. hieu van nam cuc ban ((thanh di) OR (thanh do)) cua te*".
