studies expression » studying expression, student expression, bodies expression
information trace » information grace, information trades, information space
array profiling » array processing, microarray profiling
trace studies » tracer studies, trade studies, race studies
array string » array strong, arrays strings, array sharing

• If you are trying to use Boolean operators, they must be ALL CAPS: information trace studies expression ((array string) OR (((array format) OR (array profiling)))).
