Python IntelliJ style 'search everywhere' algorithm

I have a list of file names in python like this:

HelloWorld.csv
hello_windsor.pdf
some_file_i_need.jpg
san_fransisco.png
Another.file.txt
A file name.rar

I am looking for an IntelliJ style search algorithm where you can enter whole words or simply the first letter of each word in the file name, or a combination of both. Example searches:

hw -> HelloWorld.csv, hello_windsor.pdf
hwor -> HelloWorld.csv
winds -> hello_windsor.pdf

sf -> some_file_i_need.jpg, san_francisco.png
sfin -> some_file_i_need.jpg
file need -> some_file_i_need.jpg
sfr -> san_francisco.png

file -> some_file_i_need.jpg, Another.file.txt, A file name.rar
file another -> Another.file.txt
fnrar -> A file name.rar

You get the idea.

Is there any Python packages that can do this? Ideally they'd also rank matches by 'frecency' (how often the files have been accessed, how recently) as well as by how strong the match is.

I know pylucene is one option but it seems very heavyweight given the list of file names is short and I have no interest in searching the contents of the file? Is there any other options?
