Perhaps you should try some spelling variations:
water communication » master communication, matter communication, layer communication
technologies 1 » technologies _, technologies 4, technologies 2
information 3 » information 2
development d » development ds, development 1, development did
hei water » hei matter, i water, ii water
d afrique » l afrique, en afrique, de l'afrique
3 hei » _ hei, 4 hei
3 smt » _ smt, 3 set, 3 sme
4 smt » _ smt, 4 set

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 1 information 3 hei water communication ((3 smt) OR (4 smt)) development d afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies 1 information 3 hei water communication ((3 smt) OR (4 smt)) development d afrique.*.
