Current search engines are efficient for searching ordinary web pages. However, searching in today's evolving rich internet applications is difficult task for search engines. These evolving rich internet applications are adobe flash, adobe flex, Microsoft silverlight, Ajax and others are increasingly frequent on the web or mobile devices and are offering a high degree of interactivity to the user, by seamlessly loading content from the server without the need to refresh the page. Current search engines cannot perfectly search and index these applications. In this study we demonstrated that search engine for silverlight applications can be built. The main obstacle to achieve this goal was to extract textual information from silverlight objects, because silverlight objects are compiled into binary data packed into XAP file. These XAP files contain compiled DLLS. These DLLS contains islands of binary and textual data that can be read. This textual information is extracted and indexed is built.
