Unique meta tags on search page results?

Hi, I'm tagging all my posts, but have difficulties setting the meta title and meta description on search result pages. Search page defaults to what I've set in site.yaml. I'd like to include the searched tag in the meta title and social meta. Is this possible? I'm using Simplesearch. Right now I'm getting errors in SEMrush SEO b/c of the fact every searched page (page with /tag:xx) has the same meta title and or meta description.
