Topic-based search engines are an alternative to simple keyword search engines that are common in today's intranets. Trend analysis is an important research goal for many different industries. The temporal behavior of the topics in a topic model based search engine can be used for trend analysis. We apply a topic model approach to an online financial newspaper data and show that these topics can be used to explore prevailing trends. Furthermore we show these trends are consistent with common understanding.
