The list of improvements suggested by our partner Kaliop Poland to PIM docs:

1. Product Completeness: https://issues.ibexa.co/browse/IBX-8569
   We found no information in the user guide or dev doc on whether completeness has any impact on anything, especially on products' availability on the front.
   No, completeness doesn’t impact products' availability on the front.

2. Product attributes translations: https://issues.ibexa.co/browse/IBX-8579 
   reference in the user guide or dev doc for PIM regarding the intended behavior of PIM product attribute translations
   Attributes are not translatable.

3. Product search & attributes: https://issues.ibexa.co/browse/IBX-8585 ** 
   It would be great to make good recommendations in the user guide/dev doc, based on the above points. Product content attribute or product attribute for texts.{}
   Use field to marketing description/presentation, use attributes to represent product properties/specification.
