technologies 2 » technologies _, technologies 4
developing em » developing e, developing eq, developing amp
content 2 » content _, content 1, content 3

2 wages » _ wages, 6 wages, 7 wages
1.3 4 » 1.3 a, 1.2 4, 1.3 2

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "technologies 2 information content 2 wages compensation ((1.3 4) OR (1.3 _)) developing em africa.~".
• Adding a wildcard symbol may retrieve word variants: technologies 2 information content 2 wages compensation ((1.3 4) OR (1.3 _)) developing em africa.*.
