    Why it is in this group

    • The name "search_datasets" says "search": a word for reading.
    Description, as the server wrote it
    Search datasets by free text. IMPORTANT: check server instructions first — many common queries have a direct dataset_id you can use with query_dataset without searching. Only use search_datasets when you don't know which dataset you need.
