Perhaps you should try some spelling variations:
synthesizer » synthesizes, synthesizing, synthesisr, syntheser
synthesized » synthesisd, synthesed
synthesize » synthesis, synthese
synthesisd » synthesised, synthesis, synthesise

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: ((( synthesizer OR synthesized ) OR synthesize ) OR synthesisd )*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((( synthesizer OR synthesized ) or synthesize ) or synthesisd )*".
