Perhaps you should try some spelling variations:
information environments » information environment, simulation environments
environments debra » environments data, environments dewi, environments deep
debra dimensional » zero dimensional, data dimensional, extra dimensional
array from » arrays from, gray from
ray from » rays from, gray from, way from

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

• If you are trying to use Boolean operators, they must be ALL CAPS: information environments debra dimensional ((((array from) OR (ray from))) OR ((rays OR ray) from)).
• Adding a wildcard symbol may retrieve word variants: information environments debra dimensional ((((array from) or (ray from))) or ((rays or ray) from))*.
