Enterprise search meetups are an opportunity to get together with other people doing search. Grab a drink, be challenged by one or two search-related talks, and join in the discussion. Topics can cover everything from ranking algorithms, to working with Solr and the Google Search Appliance, to designing the user interface. It's also a great way to network and stay on top of the latest developments in search.
These events are NOT about SEO or search engine marketing.
