First, it separates the Timpi network from the search users, meaning at no point is it possible for an attacker to compromise a Collector or Guardian Node. The second role is handling and coordinating search requests from the web server. The GeoCore determines whether the request can be served from the local cache or sent to the Information Broker, which coordinates the Guardian connections. The third role is the request analysis in terms of the search term, spelling, word vector analysis, historical behaviour synonym analysis, and lexical synonym analysis. GeoCore Nodes are spread worldwide to ensure all requests are served fast and accurately.
