Perhaps you should try some spelling variations:
information documents » information documentation, information agents, information requirements
component processing » components processing, component processes, compound processing
microarray profiling » microrna profiling
documents component » document components, documents complete, documents common
array string » array strong, arrays strings, array sharing

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 documents component processing ((array string) OR (microarray profiling))~.
• Adding a wildcard symbol may retrieve word variants: information documents component processing ((array string) or (microarray profiling))*.
