Does DTP search files that are attached to a PDF document ?
No. Attachments of rich text documents are ignored (but on the other hand - why attach a PDF to a RTF if you could also add the PDF directly to the database?).
Highlighting of phrases still has some minor issues, e.g. if you’re searching for “devon technologies”, then DT will highlight this phrase but not “devon-technologies” for example. This will be improved in the next releases.
