The common way to do this is to pull the matches into a register:

:let @a='' | g/pattern/y A

This will gather all the lines matching "pattern" into the "a"
register which you can paste within vim

:new
"ap

or assign to the system clipboard:

:let @+=@a

If you have multiple search terms, you can (as you mention) build the
expression out of the gate (or incrementally thanks to Vim's
command-line history):

:let @a='' | g/pattern1\|pattern2\|pattern3/y A

That is what I usually do when I want this functionality.

If you want to build it incrementally by searching instead, you can
use the search register, recall the previous search, and append your
additional term

/pattern1<cr>
/<up>\|pattern2<cr>
[repeat until you have all the terms you want]
:let @a='' | g//y A

There might be some plugins that simplify these actions, but under
the hood they would likely do the same thing as this.
