Semantic search

Keyword search fails at events more than almost anywhere else, because visitors and exhibitors describe the same thing in different vocabularies. The buyer searches "packaging machines"; the exhibitor wrote "end-of-line automation solutions"; keyword search returns nothing and both sides lose. Semantic search closes that vocabulary gap, and the commercial effect is direct: every failed directory search is a lead an exhibitor never received and a visitor who left thinking your show didn't have what they came for. In practice, semantic search arrives as a feature of your event app or matchmaking platform rather than something you build, and your job is feeding it: complete exhibitor profiles, decent product descriptions, session abstracts that say what the session actually covers. The common mistake is judging it by a quick demo search on an obvious term — keyword search handles obvious terms fine. Test it with the awkward, jargon-heavy queries your real audience types, pulled from last year's search logs if you have them. One honest nuance: semantic search returns something for almost any query, including bad ones, and a confident-looking list of loosely related exhibitors can be worse than an honest "no results." Check what nonsense queries return before your attendees do.
