Could you please try with element template or category and check if that works? Element name wild characters generally works for AF analysis.
As Lal Babu Shaik mentioned, general search criteria like Element name wildcard search, Analysis status (Running, stopped, Warning, Error) search, Analysis Enabled or disabled status will work. Following are the additional options you can use based on your analysis setup,
1. You can search with Element Template Name if you have configured the AF elements based on the Element Templates.
2. If you want to search your analysis easily, you can set the Analysis category for all your analysis created. If you have the huge number of analysis, you can set the category using PI Builder.
