If you’re in the projects page, you can use the search bar to help you find the desired project. The search filters by:
the project’s friendly name
the project’s service name
the name of the entities added in the project
From R2.4+ you can search for a project based on the entities it exposes. For this just start typing an entity or a custom entity’s name. A project will be displayed if either the project’s friendly or service names match, or if any exposed entity matches the search word.
