uv can not find a package for an existing version #11089
Description
Summary
In our corporate index, we have a package xxx with the same name as a package in pypi.
We use a virtual index in artifactory to resolve the packages, and when i query the simple index, it will find all packages (both from pypi and our local index).
It looks something like this, where the smaller version is in pypi, the higher in the local index:
xxx-0.1.tar.gz xxx-24.25.0-py3-none-any.whl xxx-24.25.0.tar.gz
When i run uv (even with no cache and index-strategy unsafe-best-match), it will not find the package at all. When running straight with pip, i have no issues at all. When i click the link to the index, it will show me the full list like above.
