Description

Hi Everyone,

Is there any way of adding more vocabulary to a Field object that already has had its vocab built?

for example if at one point I have run this sort of code:

TEXT = field()
TEXT.build_vocab(dataset_a)

Is it possible to add vocab to TEXT from another dataset without erasing the current vocab built from dataset_a?

Thanks!

Research direction
Investigate the `Vocab` class methods such as `extend` or `append`; alternatively, consider building a new vocab from combined data using `build vocab from iterator`.
