• Performing a fuzzy search may retrieve terms with similar spellings: va sac ky nang x hoi. hieu vien cac duc va ((danh doi) or (((thanh doi) OR (thanh moi)))) cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: va sac ky nang x hoi. hieu vien cac duc va ((danh doi) OR (((thanh doi) OR (thanh moi)))) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "va sac ky nang x hoi. hieu vien cac duc va ((danh doi) or (((thanh doi) OR (thanh moi)))) cua te".
• Adding a wildcard symbol may retrieve word variants: va sac ky nang x hoi. hieu vien cac duc va ((danh doi) or (((thanh doi) OR (thanh moi)))) cua te*.
