As noted in the Known limitations of Telerik Reporting
thread, currently we don't offer search. This functionality makes sense and we would consider including it in subsequent versions. In the meantime to improve the navigation within the reports our suggestion is to use a Document Map
if applicable for your scenario. Additionally you can export the report to a format such as PDF, Excel or Word where searching is accomplished by the viewing software.
All the best,
the Telerik team
