Search results from the Search page can be filtered by which folder they come from.

Filtering by Folder

Step 1: Run the search using the terms you want to look for. The initial results table will display all results found for the terms searched.

Step 2: The left side of the search page will list out all folders present in your project, and detail which folders contain documents that include the terms you are looking for. You can filter out results from any folders or sub-folders you do not want by un-ticking the box next to them.
