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