one use case we're handling right now is for a large online auction marketplace. they needed to automatically categorize 40,000 newly uploaded images per week. no tags, no metadata from the sellers, just raw photos. elasticsearch can't look at an image and tell you it's a vintage rolex or a mid-century lamp. they needed search that understands visual content, not text

that's the kind of problem where keyword search doesn't apply at all, no matter how good the engine is
