• Performing a fuzzy search may retrieve terms with similar spellings: te cach tu nang cho hoc. ((((hieu ve) OR (hieu van))) or (hieu va)) cac vuc van hanh vi cua cay~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te cach tu nang cho hoc. ((((hieu ve) OR (hieu van))) OR (hieu va)) cac vuc van hanh vi cua cay*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te cach tu nang cho hoc. ((((hieu ve) OR (hieu van))) or (hieu va)) cac vuc van hanh vi cua cay*".
