Description:
Coming from using MS Word since version 4 (1990), probably the single greatest feature missing from LibreOffice Writer is the ability to search and replace Paragraph marks, New line marks, Tabs, and so on.  For example, if I import (copy/paste) some text into Writer and it has two paragraph breaks between paragraphs, but I only want one, in Word, I would find-replace ^p^p^p with ^p^p.  

There seems to be no feature to do something like that in Write.  If I wanted to change line breaks to paragraph marks in Word, I could find-replace ^l with ^p.  

I've tried many suggestions, but none of them seem to be able to do it.  I even installed 3rd party "Alt. Find & Replace" and it can't do it reliably either.

This was a feature I would use nearly every day in Word.  Now, I have to use a manual delete/edit process in Writer.

Steps to Reproduce:
1.Create the situation by making four paragraphs in a Writer document with two "blank lines" between each.
2.Invoke the Edit > Find and Replace
3.Try to find the end of each paragraph and the two blank lines in a search.  There seems to be no control information that can be placed into the Find and Replace fields to find them.


Actual Results:
LibreOffice Find and Replace cannot find the end of a paragraph, whether it is a paragraph with text, or a blank line paragraph.

Expected Results:
I would like to be able to find the end of a paragraph in Writer search.  For example, if there is a paragraph with two blank lines following it in MS Word, I would search ^p^p^p.
If I would like to remove one of the blank lines, in MS Word, I would find ^p^p^p and replace with ^p^p.  This would remove one of the blank lines.

The first ^p finds the end of the paragraph and the subsequent ^p's identify the blank-line paragraphs.

The ability to search other text control characters is desired as well.
