• Performing a fuzzy search may retrieve terms with similar spellings: tu san ky ((((nang xa) OR (nang ma))) or (lang xa)) hoi. hieu ve cam tuc va tinh vi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu san ky ((((nang xa) OR (nang ma))) OR (lang xa)) hoi. hieu ve cam tuc va tinh vi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu san ky ((((nang xa) OR (nang ma))) or (lang xa)) hoi. hieu ve cam tuc va tinh vi cua tre".
• Adding a wildcard symbol may retrieve word variants: tu san ky ((((nang xa) OR (nang ma))) or (lang xa)) hoi. hieu ve cam tuc va tinh vi cua tre*.
