After one night sleeping on it 
, I think my solution is not the desired one.
After all, wat I thought to be synonyms actually are different entity (types).
F.e. “SSD” is the entity ‘product’ and “Computers and electroniscs” is the entity ‘catagory’
So I’ll extract the entity ‘product’ and I’ll use a look-up in actions.py to get the category by the extracted product.
And of-course, when my bot is going live, the look-ups will be stored inproduct-database
