Perhaps you should try some spelling variations:
"heart module example" » "heart modules example", "heart modules examples", "heart mode example", "health module example", "heart model example", "art module example"
"heart models example" » "heart models examples", "heart model examples", "heart modeling example", "heart model example", "bert models example", "earth models example"
"fear model example" » "fear models example", "ear model example", "gear model 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 model example") OR ((("heart module example") OR ("heart models example")))).
• Removing quotes may allow a broader search: (( fear model example ) or ((( heart module example ) or ( heart models example )))).
• Adding a wildcard symbol may retrieve word variants: (("fear model example") or ((("heart module example") or ("heart models example"))))*.
