Perhaps you should try some spelling variations:
un communication » 3 communication, 4 communication, 1 communication
technologies 2 » technologies _, technologies 4
5.5 developing » 25.5 developing, 5.15 developing, 1.5 developing
costs 5.5 » costs 3.5, cost 5.5, costs 2.5
bank die » banken die, bank deep, bank dco
bank aid » band aid, bank card, bank adb

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 ((bank die) OR (bank aid)) un communication costs 5.5 developing _ aes.~".
• Adding a wildcard symbol may retrieve word variants: technologies 2 information ((bank die) OR (bank aid)) un communication costs 5.5 developing _ aes.*.
