Thanks for the reply. I was searching for "wv" and found this thread: How to install wv to index Word documents?
There it was explained that wv was needed for the older doc file type. docx is xml based and needs Products.OpenXml.
I added Products.OpenXml to the eggs list but the build out command resulted in errors. Chat GPT explained:
- Products.OpenXml is not compatible with Python 3.
- Plone 6.1, however, requires Python 3.
Any other ideas? Did somebody solve this problem?
