One of the time-saving setting you can add to your eclipse preferences is to limit your file searches to your source code, and exclude 3rd-party folders. Such folders may include .git, .svn, cache or templates_c folder from smarty. There are a few different ways to accomplish this.
1. On the Eclipse File Explorer, right click on the folder that you want to exclude and choose "Properties". On the "Resource" screen, mark a folder Derived. Derived folder is excluded from search by default.
