I’ll give a small example of my problem. (It’s not the actual use-case)
So I want to fill a slot in a form with the entity in\_stock which can have 2 values: available or not\_available.
In my nlu file I added my entities that all map to available. Under synonyms I added those entities under available as well:
```auto
- synonym: available
examples: |
- pear
- apple
- banana
```
Now, when I ask the user what products would you like to check, this works well when the user wants to check available products. When the user enters pear, the slot in\_stock gets set to available and my actions work as planned. However, when a user enters a product that’s not available, RASA doesn’t recognize that product as the entity in\_stock with value not\_available because i didn’t define it.
How can I still set the in\_stock slot to not\_available when the user enters out of stock items or items i didn’t think of. Rasa doesn’t recognize those as an entity. I thought of making synonyms for not\_available but there are so many options.
