### Description
The filename criteria searched the full file path and as such does not
work as expected.
**This is a new feature**:
No
**I have updated the documentation to reflect these changes**:
No docs changes are required as this is fixing a bug to make things work
as expected and documented.
### Testing Notes
**What I did:**
I uploaded some files, and tested that the file name criteria worked as
expected.
**How you can replicate my testing:**
Spin up the stack, upload some files and make sure the filename criteria
works as expected.
