Search on website should find packages whose name matches substring

E.g. searching for sherpa (or Sherpa): https://search.f-droid.org/?q=sherpa&lang=en fails to find any package:

It looks like F-Droid does not have any apps matching your search string "sherpa"

One has to search for exact package name SherpaTTS to find it:

It would be nice if search for sherpa would also find SherpaTTS package (like it does in F-droid client android app)
