Search in a PDF

There might be an obvious answer to this but i cant figure it out

Can you search within a PDF in the devonthink viewer. Currently i’m having to launch preview to enable a search within a PDF

I do a search in the devonthink viewer using the Edit menu (Edit>find>find…) and have no trouble getting results. How are you searching?

In addition to searching using the Edit menu, you can search in the toolbar, using the option ‘In Selection’, and then Command-G and Shift-Command-G to step forward or back to each occurrence of the search term.
