Python -- Search Subsrtring Full Word(s)

I want to find the number of times a substring occurred in a string. I was doing this

termCount = content.count(term)

But if i search like "Ford" it returned result set like

"Ford Motors"         Result: 1 Correct
"cannot afford Ford"  Result: 2 Incorrect
"ford is good"        Result: 1 Correct

The search term can have multiple terms like "Ford Motors" or "Ford Auto". For example if i search "Ford Motor"

"Ford Motors"               Result: 1 Correct
"cannot afford Ford Motor"  Result: 1 Correct
"Ford Motorway"             Result: 1 InCorrect    

What i want is to search them case insensitive and as a whole. Mean if I search a substring it should be contained as a whole as a word or a phrase (In case of multiple terms) not part of the word. And also I need the count of the terms. How do I achieve it. Thanks in advance.
