Perhaps you should try some spelling variations:
"synthesisdr" » "synthesiser", "synthesisers", "synthesis"
"syntheseort" » "syntheseroute", "synthesenetz", "synthesezeit"
"synthesized" » "synthesisd", "synthesed"
"synthesize" » "synthesis", "synthese"

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: (("synthesized" OR ("synthesisdr" OR "syntheseort")) OR "synthesize").
• Removing quotes may allow a broader search: (( synthesized or ( synthesisdr or syntheseort )) or synthesize ).
• Adding a wildcard symbol may retrieve word variants: (("synthesized" or ("synthesisdr" or "syntheseort")) or "synthesize")*.
