Regular expression to extract whole sentences with matching word

I would like to extract sentences with the word "flung" in the whole text.

For example, in the following text, I'd like to extract the sentence "It was exactly as if a hand had clutched them in the centre and flung them aside." using regular expression.

I tried to use this .*? flung (?<sub>.*?)\., but it starts searching from the beginning of the line.

How could I solve the problem?

As she did so, a most extraordinary thing happened. The bed-clothes gathered themselves together, leapt up suddenly into a sort of peak, and then jumped headlong over the bottom rail. It was exactly as if a hand had clutched them in the centre and flung them aside. Immediately after, .........

Solution 1:

Here you go,

[^.]* flung [^.]*\.

OR

[^.?!]*(?<=[.?\s!])flung(?=[\s.?!])[^.?!]*[.?!]

Solution 2:

Simply anything between dots:

without a dote

[A-Za-z," ]+word[A-Za-z," ]+

with a dote

[A-Za-z," ]+word[A-Za-z," ]+\.

Solution 3:

"[A-Z]\\s?\\w*\\s?(([^(\\.\\s)|(\\?\\s)|(!\\s)])|\\s)*(?:your target\\s)(([^(\\.\\s)|(\\?\\s)|(!\\s)])|\\s)*(([^(\\.\\s)|(\\?\\s)|(!\\s)])|\\s)*[\\.|\\?|!]"

A sentence starts with any capital letter, in the middle it may contain decimal or abbreviation.
