Detailed search in selector

Hello, As it seems it is not possible to have a detailed search component in selector pages. When doing a research, it doesn't filter the results, but instead prints another page (inside the selector), as if we were using the application through the selector. I noticed that this happens in the following scenarios :

• In the portal
• In pages such as administrating send email type of workflow action

See the screenshots below : Thanks, Romain PENNES.
