Hi Skye,
I invite you to consider our Extract Document Text solution (and its backstory video), which we created several years ago and had retired, but have now reinstated so you and others can put it to good use.
As per the screenshot below, it allows you to schedule and automatically extract text from PDFs, docx, and doc files stored into custom parameters you can then search for a particular word or phrase.
There is a bit of setup involved, as per the video above, and it is currently configured to work with document(s) on a Task, then storing the file contents in special custom data on that Task, thereby providing two many to many levels (Project to Task, Task to Document) you can leverage.
Once Workfront offers Full Text Searching (which as I understand it is on the roadmap, but in line behind a few prerequisites), I expect we will once again retire this solution.
If you'd like more information, you're welcome to email me at doug.denhoed@atappstore.com
Regards,
Doug
