n.b country » 2.0 country, 1.4 country, 3.2 country
old country » oecd country, poland country
3d country » 3rd country, end country, cdn country
3 country » _ country, a country, 2 country

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: %((22imf staff) OR (imf staff)) country report%((n.b country) OR (((((3d country) OR (old country))) OR (3 country)))) report%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((22imf staff) or (imf staff)) country report%((n.b country) or (((((3d country) OR (old country))) or (3 country)))) report%22".
• Adding a wildcard symbol may retrieve word variants: %((22imf staff) or (imf staff)) country report%((n.b country) or (((((3d country) OR (old country))) or (3 country)))) report%22*.
