~For readability purposes, can the directory be renamed to semantic_search?~

Also, we have another contributor who is adding a workload under the same name. It'd be better to make the workload name more specific than semantic_search (such as noaa_semantic_search).

Makes sense, I'll rename to noaa_semantic_search
