x = re.search("^Love.*OK$", document)

I want to get follwing text: apples ornages pears jeep plane car water cola coffee

Solution

We can try using your current regex pattern (modified slightly) eith re.findall, to find all substring matches. Then, join the resulting array together as a single string.

document = "This is a document with random words Love apples oranges pears OK some thing Love jeep plane car OK any more Love water cola coffee OK bra bra."
matches = re.findall(r'\bLove (.*?) OK\b', document)
print(' '.join(matches))

This prints:

apples oranges pears jeep plane car water cola coffee

Explanation:

The regex pattern \bLove (.*?) OK\b will capture the content between each Love ... OK set of markers. This generates, in this case, three substrings. We then join the output array from re.findall into a single string using join().
