@monsieurtanuki I added a normalized tags list

[teolemon]

additives : with, without, indifferent We could have a suggested values for those: https://github.com/openfoodfacts/openfoodfacts-dart/blob/55f3fa583a535ec842db87067019ed2933f75a78/lib/model/parameter/TagFilter.dart like 1,2,3,4 for nova_groups (note those values are available in the taxonomies, most of the time)

[teolemon]

I added some missing link to the wiki documentation, that should clarify a number of things

[teolemon]

As a FYI, We're going to swap the backend providing the Product Opener search to the Elastic one, but the API should stay the same. cc @raphael0202 @alexgarel @monsieurtanuki

Actually, I just got word that we should aim for the newer API.
