• Performing a fuzzy search may retrieve terms with similar spellings: te sach ((thu nang) or (thu bang)) xa hoi. ((hieu ve) OR (hieu va)) cham doc va hanh dai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((thu nang) OR (thu bang)) xa hoi. ((hieu ve) OR (hieu va)) cham doc va hanh dai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((thu nang) or (thu bang)) xa hoi. ((hieu ve) OR (hieu va)) cham doc va hanh dai cua tre*".
