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