The current implementation of the Advanced Filter fails when searching for photo filenames (a.k.a. “Titles”) that contain a string of characters that are not located at the very beginning of the filename. Essentially, the “contains” option functions equivalently to “begins with” OR “is” options, but is unable to parse filenames for the desired embedded character string.
For example: a search for Title->contains “IMG_2001” retrieves the image of the quoted filename, whereas a search for Title->contains “2001” reports no results.
