• Performing a fuzzy search may retrieve terms with similar spellings: thu sac ky lang xa hoi. hieu van cao ((suc va) or (luc va)) ((phan vien) OR (phan kien)) cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sac ky lang xa hoi. hieu van cao ((suc va) OR (luc va)) ((phan vien) OR (phan kien)) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sac ky lang xa hoi. hieu van cao ((suc va) or (luc va)) ((phan vien) OR (phan kien)) cua te".
