rookie warning Can I search files from dired?

[bp1497]

I have dired showing me all the files in a directory, can I execute
some kind of search on these files from the dired screen.

I know I can do M-x shell, grep some_thing files.

I've used vim for the last 17 years and have changed jobs.  This
location does not have vim installed but does have emacs.  I prefer it
to textedit or vi
