DNF man:
...By default the command will only look at package names and summaries,
failing that (or whenever all was given as an argument) it will match
against package descriptions and URLs...

yum man:
...By default search will try searching just package names and summaries,
but if that "fails" it will then try descriptions and url...

I get the same result from "dnf search" and "yum search". It wasn't found
in package name nor summary so it's searched in description.

DNF doesn't match substrings by default in (what)provides command. You have to use '*':
e.g. `dnf whatprovides *libtoolize` [1]. Although DNF doesn't show what file it matched
from the package. We already have this reported in BZ [2].

Btw fedora devel list doesn't serve for reporting DNF bugs. Next time see the yum x dnf
differences page [3] and eventually file it here [4], please, so we have it tracked ;).
Thanks.
