Hi Артур,

That's because Vim's "branch" ("\&") in a pattern is not part of POSIX
regular expressions (neither basic, nor extended).

man ex

REGULAR EXPRESSIONS
 ex/vi supports regular expressions (REs), as documented in re_format(7),
 for line addresses, as the first part of the ex substitute, global and v
 commands, and in search patterns.  Basic regular expressions (BREs) are
 enabled by default; extended regular expressions (EREs) are used if the
 extended option is enabled.  The use of regular expressions can be
 largely disabled using the magic option.

Drop it and you'll have a BRE :^)

Regards,

Raf

>From what I can see your regex is the same as Attiva.*XXL[1],
so why not just that one?

Or what pattern are you trying to match exactly?

[1] use both /Attiva\&.*XXL and /Attiva.*XXL in vim with :set hlsearch
