Actually, `icicle-occur' (C-') is sufficient for what you requested - no
need for the extra features of `icicle-search' (C-`).

Use a prefix argument (C-u C-') to search multiple buffers. Choose the
buffers (C-mouse-2) to search, or use C-! to search them all. Type the
string or regexp you want to search for. Then use C-next to navigate among
the search hits.
