Perhaps you should try some spelling variations:
"synthesisd" » "synthesised", "synthesis", "synthesise"
"synthesisdr" » "synthesisedr", "synthesisr", "synthesiser", "synthesisers", "synthesis"
"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: (("synthesisd" OR ("synthesisdr" OR "synthese")) OR "synthesize").
• Removing quotes may allow a broader search: (( synthesisd or ( synthesisdr or synthese )) or synthesize ).
• Adding a wildcard symbol may retrieve word variants: (("synthesisd" or ("synthesisdr" or "synthese")) or "synthesize")*.
