How to search any word in linux 'screen'

I am going screen logs of devstack with following command.

screen -x stack

I find searching in screens very difficult. Currently I start copy mode with
Ctrl
A
Esc
and read all the logs, sometimes it is very irritating to go through all logs while searching for a single word.

Is there a good way for searching a word in screens?

from
man screen
I found

Searching:
/ Vi-like search forward.
? Vi-like search backward.
C-a s Emacs style incremental search forward.
C-r Emacs style reverse i-search.

but screens do not support vi-like forward search.

Answer

Once you are in scrollback mode with Ctrl + A, ESC, you should be able to search backwards through the buffer as described in the manual.

So to search for the word "string", press Ctrl + A, ESC, enter ?string and press Enter. It will take you backwards through the buffer to the word string. Pressing N will go to the next match (backwards) in the buffer.

To search forwards, the cursor should be anywhere but the end of the buffer, then use /string to search down.
