Perhaps you should try some spelling variations:
"electrical engineer's" » "electrical engineering", "electrical engine", "electric engineering"
"electrical engineers" » "electrical engineering", "mechanical engineers", "chemical engineers"
"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 line"))) OR ("electrical engineers")).
• Removing quotes may allow a broader search: (((( electrical engineer's ) or ( electrical line ))) or ( electrical engineers )).
• Adding a wildcard symbol may retrieve word variants: (((("electrical engineer's") or ("electrical line"))) or ("electrical engineers"))*.
