That's what I meant when I suggested using a different search UI.  It is
confusing to provide isearch keys with nothing more common with isearch.

If highlighting of the matches on the rendered images is impossible,
what do you think about the following approach: display the plain text
of the current page below its rendered image (just where you currently
display the page information like "Page 1 of 1"), and let isearch to
operate on this text with all its standard features: highlighting of
all matches, etc.

Isearch on the plain text will provide enough cues to visually locate
the place of the found string on the rendered image.
