If font designers did that, and if PDF readers looked at the glyph
names according to Adobe's directions, then searches would work
regardless of PUA use. However, not all fonts and not all readers do this.
My experience is that "not all" = "none." I've tested my own font
(Junicode) in Adobe Reader, Preview, Evince and Goodreader (with PDFs
generated by XeTeX), and the result is the same in all. Standard
ligatures (those encoded at FB00 and following) work fine, but others do
not. For example, Junicode has an f_t ligature in the PUA, properly
named, and when that is used you cannot search for "after" or "often" in
any of those PDF readers. But when I move it out of the PUA into an
unencoded slot, it works fine.
Same with Libertine.
