• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach ky) OR (sach y)) dang cay phoi. nhieu viec cam xuc va ((tinh di) or (tinh da)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ky) OR (sach y)) dang cay phoi. nhieu viec cam xuc va ((tinh di) OR (tinh da)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) OR (sach y)) dang cay phoi. nhieu viec cam xuc va ((tinh di) or (tinh da)) cua tre".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ky) OR (sach y)) dang cay phoi. nhieu viec cam xuc va ((tinh di) or (tinh da)) cua tre*.
