Search function like WSUS currently has for searching patch names and descriptions

That's an excellent work around there! But I do agree that a universal search function would be ideal. Thank you for the information!

Greetings Doug.

I agree, a universal search feature would be a great thing to have, not just for searching updates in the WSUS collection, but that feature could also be used to search a collection of Third-Party Updates in the Software Publishing node, or for an individual computer in a collection of dozens or hundreds of computers in a group.

One thing I will note, though, is that a similar capability does exist in the product today. From the update Title column of an Update View, you can invoke a "Contains" filter on the column, which will functionally give you a search result based on the content of that column. For example, here I've "searched" on "Internet Explorer 11":

The limitation, of course, is that it's not universal across the entire product; it's limited to a single node of the navigation tree.
