Perhaps you should try some spelling variations:
i communication » ii communication, ai communication, 3 communication
technologies 1 » technologies _, technologies 4, technologies 2
developing 1 » developing _, developing a, developing e
costs 4 » costs _, costs a, costs 4.4
1 areas » 1 area, 2 areas, 4 areas
die i » die im, die _, did i

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

• Performing a fuzzy search may retrieve terms with similar spellings: technologies 1 information _ die i communication ((costs 4) OR (costs 4.2)) developing 1 areas.~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "technologies 1 information _ die i communication ((costs 4) OR (costs 4.2)) developing 1 areas.*".
