Search functionality with # on the search query not working with multiple pages

The search functionality is not working properly for search query with an # symbol at the beginning.

For example in our repository we have the issues marked with an id (e.g. BCLOUD-11932).
When we try to search commits with this id it works, but if the issues has too many commits and so it has a Next page button, when we try to go to the next page it won't display commits related with the initial query.

I used dev tools and found out the first time we query for the issue BCLOUD-11932 this are the Query String Parameters:

#!js
search: BCLOUD-11932
_pjax: #commits .pjax

When we click on the Next page:

#!js
page: 2
search: 
_pjax: #commits .pjax

The Next page query ignores the initial query.
