# Regular Expression "\n" doesn't work

Searching for "\n" with Regular Expressions clicked finds nothing in a book long document. Any idea what the issue is? Searching "$" does find the end of paragraphs, so I know search and some regular expressions are working. edit retag close merge delete ## 2 Answers Sort by » oldest newest most voted @erad67 In a German forum for OpenOffice a Mac user complained about the same problem. Neither the regular tool nor AltSearch.oxt did their work regarding \n. On LInux and Windows no problems. See: https://de.openoffice.info/viewtopic.... (German) Please provide us with your used versions of OS and LO - and specify your query regarding David's reply. more ## Comments @Grantler - it works just fine on my Mac (running Yosemite + LibO Vanilla 6.0.3.2). I wonder what the problem was for that OpenOffice user. (And it seems 4.1.5 is their current release.) Seltsam! :/ ( 2018-04-27 20:19:17 +0200 )edit It doesn't work on my mac (Mojave and 6.1.2.1) and it's driving me nuts. Doesn't recognize either \n or$.

Actually, it does work. This behaviour is expected. To quote from the document linked, in LibO regex, \n varies whether it is in the "find" or "replace" field. It behaves as follows:

• Represents a line break that was inserted with the Shift+Enter key combination. To change a line break into a paragraph break, enter \n in the Find and Replace boxes, and then perform a search and replace.
• \n in the Find text box stands for a line break that was inserted with the Shift+Enter key combination.
• \n in the Replace text box stands for a paragraph break that can be entered with the Enter or Return key.

So, to sum up -- and as you have partially discovered -- in LibO regex, \n in FIND matches a line break; \$ in FIND matches a paragraph end.
