• Performing a fuzzy search may retrieve terms with similar spellings: te sach y ((nang xa) or (lang xa)) hoi. hieu ve chat lua van tuan van ((chu tre) OR (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y ((nang xa) OR (lang xa)) hoi. hieu ve chat lua van tuan van ((chu tre) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y ((nang xa) or (lang xa)) hoi. hieu ve chat lua van tuan van ((chu tre) OR (cuu tre))*".
