I am using a lookup table for entity extraction. The values that have spaces in them are not getting captured as entities though the exact value is present in the lookup table. Can you suggest please

Hi @poo

could you please provide us with your training data for those entities? I assume you have considered the Note on:

> **[NLU Training Data](https://rasa.com/docs/rasa/nlu-training-data/)**
>
> Read more about how to format training data with Rasa NLU for open source natural language processing.

regarding the fact that using lookup tables need training samples to work?!

Hi @JulianGerhardI have about 10000 values in the lookup table. I have captured the entities for few of them in the training data. Won’t that be enough?
