OK, I found myself a solution. Explanation: 1- Spotlight use info.plist to index application, which is located in the Contents folder of the app. 2- Parallels Application Portal.app/Contents is an alias to /Library/Parallels/pma_agent/Content/MacOS/pmm_app_portal/Contents, so the info.plist is not analysed. Solution: 1- Go to /Library/Parallels/pma_agent/Content/MacOS 2- Create an alias of pmm_app_portal.app 3- Copy it to the Applications folder 4- Rename it to Parallels Application Portal.app
Unfortunately, it's a workaround and the way the Parallels Application Portal is implemented should be improved.
