Hi @patsimpson2000,
You can read more about how the Description/Tags search works here:

In short, it actually searches 4 different things, also including place descriptions and taxon names on the observation. You can limit the search to just one of these areas, but for now that requires that you manually edit the URL of the search page, as described in the above linked tutorial.
To search only within tags, for example, you would add &search_on=tags to the URL of the web page. If I am reading your post correctly, I think clicking on this URL would give you what you are looking for:
