Can I search for content on DTTG with new pdf's imported on DTTG?

I have my main DT database on my iMac which is synced towards my iPhone. if I use a scanning app like scan pro on my iPhone and share the scanned doc’s towards DTTG it seems that searching for content still is not possible although they are ocr’ed. Is this correct ? However, If I import a pdf via my iMac and this doc is synced towards my iPhone then I can search for content on my iPhone DTTG?
