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