I'm searching for an app capable of indexing/searching not just PDF files content, but also the comments and revisions inside them - some of the docs I'm using have more than 1000 comments...and the Acrobat search engine, not building an index, becomes very slow.
I've yet tried PDF Search but this feature seems to lack, and Skim looks a bit outdated.
If you have any suggestions (or hints to improve my question) your help will be warmly welcome!
