You're close. You can use control+R followed by the register-name to
insert that register at the search prompt. So you can do something
like

/<C-R>b

to insert the content of the "b" register at the search prompt. Note
that this is interpreted as a regular expression, so if your register
contains regex metacharacters, you'd have to escape them. Which can
be done from a mapping with something like

:cnoremap <f4> <C-R>=escape(@b, '.\*/')<cr>

where the ".\*/" is a list of characters to escape.

You can read up more at

:help c_CTRL-R
:help @=
:help escape()

if you want the ugly details.
