Serch folder of pdfs for hasComments

[Geir5FAA]

Hi!

I have a folder of 50-100pdfs, that I work through and add comments for opdating source-files (odt and sib / text and music-scores). I do this locally win 8 and via GoogleDisk cloud (Android tablet)
Then I need to search folder for those pdfs that has comments in them (win8). Is there any way to do that?
