Perhaps you should try some spelling variations:
synthesizer » synthesized, synthesizes, synthesizing, synthesizedr, synthesisr
synthesizeddr » synthesized, synthesizedand, synthesizes, synthesizedddr, synthesisddr
synthese » synthesis
synthesize » synthesized, synthesis

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 ( synthesizeddr OR synthese )) OR synthesize ).
• Adding a wildcard symbol may retrieve word variants: (( synthesizer or ( synthesizeddr or synthese )) or synthesize )*.
