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