PDF workstation with comments added - searchable on ipad using Acrobat DC?

Hi I have a pdf on my workstation that I added comments to throughout the document.  I can search on the workstation using the index of comments on the right and it works great.  I would also like this ability on my ipad.  I can upload the document to the Acrobat cloud and access the pdf on my ipad using the Acrobat DC app.  BUT I cannot use the search icon on the bottom to search on the comments.  Is this possible?
