Perhaps you should try some spelling variations:
"electrical engineers's" » "electrical engineering", "electric engineering", "electrical engine"
"electrical engineer's" » "electrical engineering", "electrical engine", "electric engineering"
"electrical line" » "electrical life", "electrical engine", "electrical aging"

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: (("electrical engineer's") OR ((("electrical engineers's") OR ("electrical line")))).
• Removing quotes may allow a broader search: (( electrical engineer's ) or ((( electrical engineers's ) or ( electrical line )))).
• Adding a wildcard symbol may retrieve word variants: (("electrical engineer's") or ((("electrical engineers's") or ("electrical line"))))*.
