• Performing a fuzzy search may retrieve terms with similar spellings: te sach ty hang xa hoi. ((((hieu van) OR (thien van))) or (hieu va)) cam luc van thanh va cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty hang xa hoi. ((((hieu van) OR (thien van))) OR (hieu va)) cam luc van thanh va cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty hang xa hoi. ((((hieu van) OR (thien van))) or (hieu va)) cam luc van thanh va cuu tre*".
