Difficulty importing Evernote notes that contain pdf files

I have a relatively large Evernote database about 20k+ of records. I have found several ways to import individual notebooks from DT. However, all result in my pdfs being split into two files. One is the pdf name and contains a link to a second record which contains the actual pdf.

Is there any way to import so there is only one record for each Evernote note containing a pdf file?

Will these pdf files be searchable in DT?

This is the way Evernote exports your data; a note and the actual pdf
