Copy yes; search, that is not clear.

It does not touch the DOM, as you say (unless the Views module gets
revived).

EW> it will likely change what the end user gets as content.

It changes the presentation, yes. In CSS, the rendering tree is
'almost' like the content tree; or is a copy of that tree with changes
(extra elements for first line and first letter, :before and :after,
implied table and table tow, and so forth).

word-spacing and text-transform similarly affect the copy of the text
that is in the rendering tree (as opposed to using a small-caps font,
which has no such effect on the text in the rendering tree).
