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