`isearch-yank-string' can yank a regexp string as well.
If you use Isearch+ then you have option
`isearchp-regexp-quote-yank-flag':
Non-nil means escape special chars in text yanked for a regexp isearch.
You can toggle this using `isearchp-toggle-regexp-quote-yank', bound
to `C-`' during Isearch.
IOW, if you turn off this escaping then regexp search
interprets yanked regexps normally. If you turn it on
then a yanked regexp string has its special chars
quoted (escaped).
With this escaping turned off, you can yank text such
as `^\*.*' without it being transformed to `\^\\\*\.\*'.
