A colleague of mine came up with maybe a similar question and we developed some super dirty approach that might give you an idea where to look. Since all things KNIME are stored in XML files we thought we might as well import them and search for a specific term. I constructed this scenario. I have my XML search meta workflow and a workflow in a subfolder (you might use any folder you like). I want to know where someone used the term “cryptic_xy_name” somewhere in the folder/workflow.
