• If you are trying to use Boolean operators, they must be ALL CAPS: (((("tu sach toc tay nguoi") OR ("tu cach toc tay nguoi"))) OR ("te sach hoi tay nguoi"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"tu sach toc tay nguoi\") OR (\"tu cach toc tay nguoi\"))) or (\"te sach hoi tay nguoi\"))~".
• Removing quotes may allow a broader search: (((( tu sach toc tay nguoi ) OR ( tu cach toc tay nguoi ))) or ( te sach hoi tay nguoi ))~.
• Adding a wildcard symbol may retrieve word variants: (((("tu sach toc tay nguoi") OR ("tu cach toc tay nguoi"))) or ("te sach hoi tay nguoi"))*.
