isearch-lazy-highlight-new-loop

isearch-lazy-highlight-new-loop is a compiled Lisp function in `isearch.el'.

(isearch-lazy-highlight-new-loop &optional BEG END)

Cleanup any previous `lazy-highlight' loop and begin a new one.
BEG and END specify the bounds within which highlighting should occur.
This is called when `isearch-update' is invoked (which can cause the
search string to change or the window to scroll). It is also used
by other Emacs features.
