Search/filter results should display full path or directory name of a file.
Often document names only have meaning within the directory context. For example you can have 3 projects and each can have a document called UI Requirements.docx inside.
When you search for "requirements" from the main projects section you currently get 3 documents that look identical. The directory name would add very valuable context to search results. It can replace the currently redundant hover over document name text if placing on the page is not desirable.
