OCR Searchable pdf content in dspace 7+

[ruchira raul]

I have installed dspace 7.3 on ubuntu 22.04.

Kindly help me to make pdf or other file OCR searchable ie. can be searched with any content in pdf or file and not only from keywords, title, author etc.

Please let me know the settings or steps to be changed in the configuration files.

Hi,

For full-text indexing/searching in DSpace, you need to enable/run the "Media filters": https://wiki.lyrasis.org/display/DSDOC7x/Mediafilters+for+Transforming+DSpace+Content

These are scripts that can extract text out of text-based content (like OCR'd PDFs, Word docs, etc).

Most sites choose to run those on a scheduled basis (e.g. once per day, or a few times a day) via a Cron Job.  See this guide: https://wiki.lyrasis.org/display/DSDOC7x/Scheduled+Tasks+via+Cron

If you have more questions, let us know on this list.
