I can't search for more than 1 file at a time

I have a client who has chosen 200 wedding photos. In Lightroom CC, I can't seem to "search" for more than 1 file at a time. Is it possible to copy all the filenames that I need into the search bar, and have all those chosen images show up? I know it can be done in classic, just can't find it working at all in CC.
