Perhaps you should try some spelling variations:
compression concurrent » compression document, computation concurrent
concurrent programming » constraint programming, concurrent programs
functions compression » function expression, functions composition, functions computation
array processing » dairy processing, query processing
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: functions compression concurrent programming ((array string) OR (array processing))~.
• Adding a wildcard symbol may retrieve word variants: functions compression concurrent programming ((array string) or (array processing))*.
