The questioner presumably wants to merge existing paragraphs: 
removing paragraph breaks and replacing them by tab characters.

Sorry, but that's not so.  If "Regular expressions" is not ticked, 
then .$ matches exactly that: a dot followed by a dollar sign - 
nothing about paragraph breaks.  If "Regular expressions" is ticked, 
then .$ matches any single character but only if it occurs at the end 
of a paragraph.  But note in this latter case that the expression 
matches only that single character, without including the paragraph 
break itself.  So any replacement replaces the single character but 
leaves the paragraph break as it was.

The $ sign anchors any search to the end of a paragraph, but does not 
match the paragraph break itself, which - in the view of 
LibreOffice's regular expressions - does not exist as a separate 
entity.  There is no simple way to match and replace paragraph 
breaks, I think.  (You can match and replace Shift+Enter line breaks 
- using \n.)

I trust this helps.
