To dramatically enhance findability, Searchlight Tagger can automatically add metadata tags based on document content. The technical overview video below provides information on the range of automated tagging methods offered by Searchlight Tagger.
Note that Tagging requires that documents are fully text searchable. Searchlight OCR is a separate part of the Searchlight suite that can ensure that image PDFs and other image documents have Optical Character Recognition applied so that their text content is available to the tagging process as well as SharePoint text search indexing.
To run in production a fixed price license needs to be purchased from Aquaforest. You will also be charged by Microsoft Azure for the hours the VM is running.
