[Question] update vocabulary zip when new image's bow in

[leechangyo]

hello, developer.
I really appreciate your project and your work.

now I'm doing my own project that I have an image dataset(specific urban path in my case, called it as 1st image dataset) and I use yours to train images and made vocabulary zip for that image dataset(1st image dataset).

and with vocabulary zip, want to find the same image from the image dataset corresponding with an image of a place of another day in the same path(call it as 2nd image dataset) using your Dbow.

but most of the time found the wrong image with a low score from the image dataset(1st image dataset).
(if using the same image of the image dataset(1st image dataset) to vocabulary zip(1st image dataset), instead of the same image of the place of another day, it found the right image from the 1st image dataset

thus, I will try to add another day's images BoW(2nd image dataset) to the vocabulary zip already made before. (tend to update vocabulary zip)

and I wonder,
will it be okay that add a new Bow of an image(2nd image dataset) to the existing vocabulary zip(1st image dataset) and use it to find an image from the 1st image dataset corresponding to an image of the 2nd image dataset? not like creating a vocabulary zip from scratch with two image datasets again and using this zip to find the right image from 1st image dataset corresponding to an image of 2nd image dataset.
