Filter/Search only matches beginning of words? Why?

Hi.

I have a folder of hundreds of videos defined via SMB to Videos (not as a Library entry) and I like to find certain videos based on (part of its) name.
It appears the Sidebar Filter (or Search now at v17beta5) only matches from the beginning of words, not anywhere.
Is there any settings to change that behaviour?

E.g. I have file named “Party with my friends at the beach.mpg“. When I enter “end” to the filter/search I cannot see this file. I would like to.

Is there some reason filter behaves like this?

Thanks.
