You can access the search function via the magnifying glass icon in the action bar on top of the screen. When you tap on the iicon, a line appears where you can enter your search term. After entering you search term, a list with all objects containing the term will appear, e.g., if you type "cis", there will be a list with all object names containing "cis". To close the search results, tap on the x or use the arrow to go back one page.
