Notepad++ Regex Replace doesn't work on Notepad++

Question

I tried to search for every word that has
bar-foo and switch them to foo-bar
so I wrote on the find (\\w+)-(\\w+)
and on the replace $2-$1

Answer 1

Use \2 \1 in the replace field.

Notepad++ uses the linux like \1 syntax instead of $1

Answer 2

With notepad++ you'll need to use \2-\1 as the replacement string.
