Perhaps you should try some spelling variations:
reengineered » reengineer, reengineering, bioengineered, reengineers
enginered » engendered, engineer, engined
engineered » engineers
unengineered » unengineers, nonengineered, nanoengineered, bioengineered

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: (((reengineered OR (enginered OR engineered)) OR ((engieered OR unengineered) OR enineered)) OR engine).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((reengineered or (enginered or engineered)) or ((engieered OR unengineered) or enineered)) or engine)".
• Adding a wildcard symbol may retrieve word variants: (((reengineered or (enginered or engineered)) or ((engieered OR unengineered) or enineered)) or engine)*.
