• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"chinh sac dan toc.\") OR (\"chinh sach dan toc.\"))) OR (\"hinh cac dan toc.\"))~".
• Removing quotes may allow a broader search: (((( chinh sac dan toc. ) OR ( chinh sach dan toc. ))) OR ( hinh cac dan toc. ))~.
• Adding a wildcard symbol may retrieve word variants: (((("chinh sac dan toc.") OR ("chinh sach dan toc."))) OR ("hinh cac dan toc."))*.
