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