Perhaps you should try some spelling variations:
partially accelerated » partially correlated, partially integrated, naturally accelerate
particle accelerator » particle accelerators, particle acceleration
particle accelerated » particles accelerated, particle accelerators, particle acceleration
particle acceleraton » particle acceleration, particles acceleration, particle accelerations
accelerators\" » accelerate\", acceleration\"

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: "((\"particle accelerator\") OR (((\"particle (accelerators\" OR accelerating\")) or (((((\"particle accelerated\") or (\"partially accelerated\"))) or (\"particle acceleraton\"))))))".
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((\\"particle accelerator\\") or (((\\"particle (accelerators\\" OR accelerating\\")) or (((((\\"particle accelerated\\") or (\\"partially accelerated\\"))) or (\\"particle acceleraton\\"))))))\"".
• Removing quotes may allow a broader search: (( particle accelerator ) or ((( particle (accelerators OR accelerating )) or ((((( particle accelerated ) or ( partially accelerated ))) or ( particle acceleraton )))))).
