I've already figured out how to search and download Nuget packages using this guide. But I can only search by exact package name, while I want to search packages by partial name match like I do in Visual studio package manager. However, I didn't found any workarounds to achieve this functionality.
The only concept I have in mind for now is loading whole list of packages in gallery page by page and somehow look for names matching. But it appears to be too much time-consuming approach.
I'll appreciate any help and suggestions.
