• http://world.openfoodfacts.org/cgi/search.pl?search_terms=Tarchun&search_simple=1&action=process

These should find http://world.openfoodfacts.org/product/4038745603527/tarchun , but they don't.

Part of

• 🔎 Search (Tracking bug) #5492

The executed MongoDB query { '_keywords': { '$all': ['tarchun'] } } does not return the value either. One reason could be that the product_name is empty, see API, and thus they _keywords property does not contain the value.

> db.products.find({'code': '4038745603527'}, {'_keywords': 1});
{ "_id" : "4038745603527", "_keywords" : [ "тархун", "limonaden" ] }

The multilingual names are not indexed by index_product, so that kinda explains that, I guess. Maybe we need keywords for each language of the product to be indexed separately, ie. _keywords_de, _keywords_ru, etc.? However, this sounds like it could be bad to index with MongoDB …
