Perhaps you should try some spelling variations:
"synthesize" » "synthesized", "synthesis", "synthese"
"synthesisd" » "synthesis", "synthesisand", "synthesized"
"synthesise" » "synthesises", "synthesis", "synthesized"
"synthesised" » "synthesisesd", "synthesisd", "synthesizedd", "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: ("synthesize" OR ("synthesisd" OR ("synthesise" OR "synthesised"))).
• Removing quotes may allow a broader search: ( synthesize or ( synthesisd or ( synthesise or synthesised ))).
• Adding a wildcard symbol may retrieve word variants: ("synthesize" or ("synthesisd" or ("synthesise" or "synthesised")))*.
