Perhaps you should try some spelling variations:
communication collision » communication commission, communication cohesion, communication collections
dimensional array » dimensional accuracy, dimensional terrain, dimensional approach
collision based » collocation based, collision system, collision cables
dimension array » dimension area, dimensional arrays, dimension accuracy

• If you are trying to use Boolean operators, they must be ALL CAPS: communication collision based ((dimension array) OR (dimensional array)) ang*.
