Currently, LibreOffice Writer does not allow to search for the regular expression "paragraph break"/paragraph character in the Search&Replace dialog. It is only possible to search for line breaks (that was inserted with the Shift+Enter key combination), but not for a usual paragraph break. In MS Word the regular expression ^v allows find&replace of paragraph characters. I suggest this as an EasyHack. The extension AltSearch provides this enhancement: http://extensions.services.openoffice.org/en/project/AltSearch
Have you tried to do what altsearch extension does ? For me it works as expected if I search $ with "regulars expressions" checked. Tested with LO 3.5.5 RC2, LO 3.5.6.0+ and LO 3.6.0.0 beta2+ under Ubuntu 11.10 x86-64. Best regards. JBF
@Jean-Baptiste: Thank you very much for your comment. In fact, "$" works. I searched intensively the internet and everywhere it was mentioned that OpenOffice/LibreOffice is not able to search for the paragraph character. Also, the LibreOffice help page http://help.libreoffice.org/Common/List_of_Regular_Expressions does not help in this regard. I changed the title and the component of this bug to address this short-coming in documentation. Hence, I suggest to change the wording in LibreOffice help to following: $ finds the paragraph character at the end of the paragraph. "$" can be also used in combination with a search term if the term appears at the end of a paragraph. Example: "Peter$" will find the term "Peter" if the paragraph break is directly after the term. Please note: Special objects such as empty fields or character-anchored frames at the end of a paragraph are ignored.
I added David and Kendy to this bug, because both seem to have write access to LibreOffice Help and could be fixing this little issue. Please see my suggestion for wording in comment 2. Thanks.
