Problem

Searches now return the most relevant results based on a combination of many factors including version compatibility, recency, and popularity, in conjunction with text relevancy. This means that obsolete and unsupported plugins – while still available – are less prominent in search results than those in active development and use.

While that last bit focusses on “obsolete and unsupported plugins,” the same is true for plugins that are less than 24 hours old, like this one.
