How can I search on Pipeline Variables in My webMethods Portal

Hi Guys,

I have a question. How can I do the following:

a.) I would like to do search on the pipeline variables.

Say for example:

I ran the process with same set of variables on different days. I would like to do a search on the same variable and I would like to see all the processes related to the same variable that ran on different days.

How can I do that? And what properties needs to be set in Modeler? Do I have to set the properties at Model level or on each step in the model?
