Add original folder name search

I have tens of thousands of photos in a well organized hierarchical folder structure.

Many of these photos do not contain location information or date taken information since they come from older digital cameras or scans.

I was expecting that the name of the original containing folder would be available to search on, as you can the original file name.

For example

Photos\Travel\2004 Tuscon\Pima Air Museum\img1234.jpg

Right now I can search for img1234.jpg but I cannot search for "Travel", "Pima", "Museum", "Tucson" or combinations.

I strongly suggest making it an option to search on the folder name in addition to the file name.
