Perhaps you should try some spelling variations:
"synthesizedr" » "synthesized", "synthesizer", "synthesizers", "synthesizeddr", "synthesisdr", "synthesedr"
"syntheser" » "synthese", "syntheses", "synthesen"
"synthesize" » "synthesized", "synthesis", "synthese"
"synthesizes" » "synthesizeds", "synthesiss", "syntheses", "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: ((("synthesizedr" OR "syntheser") OR "synthesize") OR "synthesizes").
• Removing quotes may allow a broader search: ((( synthesizedr or syntheser ) or synthesize ) or synthesizes ).
• Adding a wildcard symbol may retrieve word variants: ((("synthesizedr" or "syntheser") or "synthesize") or "synthesizes")*.
