Limiting SharePoint Search Engine to a specific subsite -

I have a site in which there are many subsites, let's assume that the main intranet site of the company is the form of finance, information technology, Is in. I have to restrict users to search only within specific sites. Say, when a person searches from the Finance Department, the result should come only from that department. But I want them to reach all the departments, but the search results should be their own department.

You should create a custom scope and conditions on those scopes that limit the results coming from those specific areas. Should add. When searching for each region, users will see the results only with those URLs containing the initial URLs you have defined. You can limit the scope to see the scope selector (or hiding selector) to users, you will need to replace the search box embedded in the master page with your own search box (this is a representative control) your parameters) .
