Perhaps you should try some spelling variations:
"fear models example" » "fear models examples", "fear model example", "fear model examples", "ear models example", "wear models example", "setar models example"
"der module example" » "der modules example", "der modules examples", "der model example", "der modul example", "der modus example", "power module example"
"heart module example" » "heart modules example", "heart modules examples", "heart model example", "health module example", "heart models example"

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: (((("fear models example") OR ("der module example"))) OR ("heart module example")).
• Removing quotes may allow a broader search: (((( fear models example ) or ( der module example ))) or ( heart module example )).
• Adding a wildcard symbol may retrieve word variants: (((("fear models example") or ("der module example"))) or ("heart module example"))*.
