Some of the matters arising with regex can be found in the OOo archives:

Examples

This is probably too arcane, but here's a discussion on the black art of finding octal, decimal, & hexadecimal numbers in Writer http://www.oooforum.org/forum/viewtopic.phtml?t=66319

Octal   \<0[0-7]*\>
Decimal \<[1-9][0-9]*\>
Hex     \<0x[A-Fa-f0-9]+\>

Workarounds

In at least some versions of Linux it is possible to use unicode input to directly type a newline (line feed / soft line break/ U+000A) in the "Replace with" input box. There are no reports so far of this working on any other OS.

This means that for some people it is possible to insert a newline using Find & Replace.

Versioning of regex howto in future

Backreferences

http://www.openoffice.org/issues/show_bug.cgi?id=15666#desc100 describes a glitch in the new backreference feature. It does not seem to have been reported as a seperate issue, so may not get picked up. One to test for!

Capitalize words beginning with h:
s/\<h([a-z]+)/
r/H$1/
Match case = Yes

Starting text:   He heard quiet steps behind him.
Expected result: He Heard quiet steps behind Him.
Actual result:   He H$1 quiet steps behind H$1

http://qa.openoffice.org/issues/show_bug.cgi?id=84922 describes a situation where backreferences do not work in find, although I can't follow it myself.
