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