The square brackets are wildcard syntax saying "match any of the characters
listed within the brackets". This is part of the syntax of the fnmatch()
standard C function, see:
http://pubs.opengroup.org/onlinepubs/009695399/utilities/xcu_chap02.html#tag_02_13_01

The pattern you originally tried to use:

   /specs/[01234]

would match any of the following paths:

   /specs/0
   /specs/1
   /specs/2
   /specs/3
   /specs/4

But not this path, assuming '[01234]' is a literal part of the filename:

  /specs/[01234] product x spec.pdf

The pattern you ended up using is a better way of matching those paths:

  /specs*01234*

You should be able to quote the square brackets with a backslash to prevent
them from causing wildcard matching. For instance, the following should
match '/specs/[01234] product x spec.pdf':

   /specs/\[01234\]*pdf
