Perhaps you should try some spelling variations:
information aggregation » information integration, information propagation, information organization
aggregation system » aggregating system, aggregation state, aggregation sites
array profiling » array processing, microarray profiling
array sharing » arrays bearing, array imaging, way sharing
array string » array strong, arrays strings, array forming
system r » system re, system ras, system rms

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 aggregation system r ((((array string) OR (array sharing))) OR (array profiling))~.
• Adding a wildcard symbol may retrieve word variants: information aggregation system r ((((array string) or (array sharing))) or (array profiling))*.
