             Bug #: 53290
           Summary: [Find and replace] Backreference is not evaluated if
                    word boundary is present in search string
    Classification: Unclassified
           Product: LibreOffice
           Version: 3.5.0 release
          Platform: All
        OS/Version: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Libreoffice
        AssignedTo: libreoffice-bugs at lists.freedesktop.org
        ReportedBy: miniopl at poczta.onet.pl


Backreference ($n) in "replace" is not evaluated if word boundary symbol is
present in "search" string.

Steps to reproduce:
1. Open new document, write to it:
#v+
what whatever what whatever
what whatever what
#v-
(there is no space after final word)
2. Open "Search and replace" dialog. Check "regular expression" in "More
options".
3. In "Search" field write:
(what)\>
4. In "Replace" field write:
$1ever
5. Hit "Replace all"

Expected output:
#v+
whatever whatever whatever whatever
whatever whatever whatever
#v-

Actual output depends on application.
1. Calc gets it all correct (as expected).
2. Impress and Draw gets it all wrong:
#v+
$1ever whatever $1ever whatever
$1ever whatever $1ever
#v-
3. Writer gets it half-correct - backreference is evaluated only if matched
word is last word in line:
#v+
$1ever whatever $1ever whatever
$1ever whatever whatever
#v-

I was able to reproduce this behavior on:
1. LibreOffice 3.6 on Windows 7, i386 (only Writer tested)
2. LibreOffice 3.5.5 on Debian, amd64
3. LibreOffice 3.5.0 on Windows 7, i386 (only Writer tested) (build id:
7e68ba2-a744ebf-1f241b7-c506db1-7d53735)

I can not check it on any earlier version of LO, but this is possible
regression.

Best regards
Mirosław Zalewski
