This does not happen on all documents, but it does on many. I can email a document to you privately if needed.

When using search, the results are grouped so that when clicking the "next" button to move to the next result, it instead moves to the next group of results. This also happens in the full advanced search (see screen shot). Match counts are incorrect and it's easy to miss matches when using the simple search to move through matches. We need the "next" button to take us to the next instance of the search term and not the next group.

I believe that this is happening due to the way the text is stored in the PDF, but regardless we need to be able to move between individual results and not groupings of results.
