If a match is found, the corresponding incident report is directly incorporated into the response, including status information and a link to the incident page. Incidents are prioritized by severity (incident &gt; partial incident &gt; maintenance &gt; warning &gt; notice).<\/li>\n<\/ul>\n<\/li>\n<li>Improved Document Search:\n<ul>\n<li>The way Ritchy accesses the IT Center documentation has been fundamentally redesigned. The search now uses a three-stage approach (keyword search, vector search, and semantic re-ranking) to retrieve more relevant articles. In addition, more document context is included in responses, resulting in more precise and complete answers.<\/li>\n<\/ul>\n<\/li>\n<li>More Reliable Language Detection:\n<ul>\n<li>Automatic language detection has been made more robust. In particular, for queries containing English technical terms (e.g., product names like Cisco AnyConnect), the system now more reliably identifies the user\u2019s actual language and consistently formulates the response in that language.<\/li>\n<\/ul>\n<\/li>\n<li>Structural Improvements:\n<ul>\n<li>The internal architecture of the application has been modularized to simplify future extensions and maintenance.
