What model is used in NER demo?

When I tried demo of NER version, I got many entities there. But when I used it in my own project it didn’t work correctly. I use ner_ontonotes_bert_mult_torch and work mostly with Russian language. Sometimes it can be English.

from deeppavlov import configs, build_model
deeppavlov_model = build_model(configs.ner.ner_ontonotes_bert_mult_torch, download=True)

And I get in two times less entities then in demo version. What do I do wrong?
If it really need, I can show some examples of the text.
