Detecting multiple regexes as separate entities

Rasa Open Source
1

Hi,

I have a few regexes in my Rasa application, it’s able to pick up one of them as an entity but not all of them. Here are the regexes and examples:

product-id --- '\d{7}$'        1234567   
category-id --- '[CA]\d{5}$'   CA12345
product-id --- '[PD]\d{7}$'   PD1234567

Product-id is always picked up, however, if any combination of the other appear in an utterance they’re not detected at all.

How can I get Rasa to pick up all of them?

Thanks

Hi @qamir ,

could you share your config and nlu examples including these entities?

I’d need some info on what you’re using to be able to help you out.

Regards, Nikola
