When creating a graph or report you can search according to the Query Name, Title, Module, BO, and/or Tag. Ensure you are searching by the right parameter!
In Version 1.8.0 and onward we changed from using System Reports to Community Reports. Ensure you have checked off the query as being a Community Report in order to search for it in Kurve. Additionally, you are able to use multiple parameters to search! Check that your parameters are all correct.
