• Performing a fuzzy search may retrieve terms with similar spellings: thuat ((sach ly) OR (sach y)) ((nang xa) or (lang xa)) hoi. hieu van cam lo can hanh di cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat ((sach ly) OR (sach y)) ((nang xa) OR (lang xa)) hoi. hieu van cam lo can hanh di cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat ((sach ly) OR (sach y)) ((nang xa) or (lang xa)) hoi. hieu van cam lo can hanh di cua te*".
