Perhaps you should try some spelling variations:
water communication » master communication, matter communication, layer communication
information data » information d820, information database, information databases
development l » development li, development 1, development law
l afrique » en afrique
a sme » _ sme, 5 sme, a see
3 sme » 3 same, _ sme, 3 smt

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 _ information data 1 water communication ((a sme) OR (3 sme)) development l afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies _ information data 1 water communication ((a sme) OR (3 sme)) development l afrique.*.
