The DayliteDocs sidebar item in Daylite allows for a global document search in your Daylite database.
The following video shows you how to use this feature (starting at minute 1:24):
To perform a full-text search, make sure Content of files is checked within the Search Criteria drop-down menu. Then enter the desired search term.
Please note that the full-text search is only possible for machine-readable documents with text that can be selected and copied (PDF files that have been created by a scanner require OCR (Optical Character Recognition) to be searchable).
Tip: Use the PDF OCR X App. Non-machine-readable documents cannot be interpreted by DayliteDocs.
