Is it possible to sort Search result current site wise?

I am working with SharePoint Online site collection. Here I am having a requirement that I have multiple sub-sites and in every sub-site I am having common lists with same name with Items.

Now I want that if I search something on the sub-site's Search box then it should first display the item from the current site from which I am searching and then from other sites.

Is it possible to work with such requirement with default search?

For Example :-

If I am searching the text using search textbox from Site-A, then the search results from Site-A should be on the top and then all other results.
