Searching annotated PDF's in a folder
I have opened a pdf file with Preview.....then opened the Tools menu...then Annotate in the drop down menu....then note. I have then added a note (annotations embedded in PDF). Now, I want to open a folder and search all the annotated PDF's in it for a particular verbiage in the notes that are embedded (without opening each individual PDF). Is this possible? Thank you!
