Thanks for the pointers. Note that in this use case I don't need to
search in the PDF file itself but in the pdf-annot-list-mode buffer that
is created via pdf-annot-list-annotations. This buffer is synchronized
with the PDF to which it is linked. What this link type does is visit
the pdf file (with pdf-tools), create the list of annotations and jump
to the specific annotation, by date.
pdf-annot-list-display-annotation-from-id highlights the specific list
annotation in the linked PDF (if necessary, moves to the corresponding
page), and opens the content of the annotation in another window
(interactively the function is executed by pressing SPC on the
annotation list at point). Storing the annotation date seemed like the
safest option to me, since the annotation id can change when adding new
annotations, each time the list is created. The typical scenario: when I
am consulting a PDF annotated by someone and I want to store the
location of some specific annotations. As there can be many annotations
per page, adding a simple bookmark to the page would not be enough
either.
