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