• Performing a fuzzy search may retrieve terms with similar spellings: thu ((sach ly) or (sach hoi)) hoang xa hoi. hieu va ((dao xuc) OR (dao xu)) va danh vai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sach ly) OR (sach hoi)) hoang xa hoi. hieu va ((dao xuc) OR (dao xu)) va danh vai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sach ly) or (sach hoi)) hoang xa hoi. hieu va ((dao xuc) OR (dao xu)) va danh vai cua te".
• Adding a wildcard symbol may retrieve word variants: thu ((sach ly) or (sach hoi)) hoang xa hoi. hieu va ((dao xuc) OR (dao xu)) va danh vai cua te*.
