cuc tre » duc tre, cua tre, cuu tre
ve cam » ve cham, va cam, ve cau

• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ky nang xa hoi. hieu ((((ve cam) OR (ve cai))) or (ve cac)) suc danh thanh tai cuc tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky nang xa hoi. hieu ((((ve cam) OR (ve cai))) OR (ve cac)) suc danh thanh tai cuc tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky nang xa hoi. hieu ((((ve cam) OR (ve cai))) or (ve cac)) suc danh thanh tai cuc tre".
• Adding a wildcard symbol may retrieve word variants: tu sach ky nang xa hoi. hieu ((((ve cam) OR (ve cai))) or (ve cac)) suc danh thanh tai cuc tre*.
