Face Recognition Deep learning

Hello

Greetings of the day!

So I researched face recognition algorithm and convolution neural networks conceptually and even did a practical implementation successfully on a dataset containing 15-20 face images.

Now I have an opportunity to implement my model in a live application where the dataset or the database is containing almost 30K face images. Although my model is already trained however searching a user face in a dataset like this could be time consuming and I want result of the face image of the user standing in front of my camera immediately.
Can anyone guide me to achieve that.
