Use the profile search to find creators by bio, topic, or similarity to other accounts. You can filter by @profile, #hashtag, or keywords — keywords match both captions and bios. You can also combine operators to refine results:

space = AND | = OR- = NOT

For example, renovation house -apartment returns bios about home renovation that don't mention apartments. Bio search is separate from caption search, so be intentional about which field you're targeting.
