Description Mirosław Zalewski 2013-06-26 13:45:18 UTC
New regex engine is great, but backreferences in Search field must be written with backslash (\1, \2 etc.), while backreferences in Replace field must be written with dollar sign ($1, $2 etc.).

This is inconsistent and brings confusion to user.

To see what I mean:

1. Create new Writer document. Write "test test"
2. Open search and replace dialog, check "Regular expression"
3. In Search enter:
in replace:
press "Replace all".
You should get "testing testing"
4. In Search enter:
in replace
press "Replace all"
Error will occur that match could not be found.
5. In Search enter
in replace
press "Replace all"
duplicated string will be deleted.

tested under LO 4.0.4, Debian testing amd64.

After reading through ICU regex list[0] again, carefully, I now know that this is intended.

I still think that this is confusing and should be changed, but this is pretty much ICU design decision, so pretty much NOTOURBUG.
