# Step 1: Locate the Search Mask

The Search Mask consists of the following elements:
* The **Search Bar,** where keywords can be entered. Pressing the ENTER key or the magnifying glass symbol at the end of the line starts a search. More about the Search Bar can be found [here](/navigating-and-searching/examples-of-typical-searches/search-functions/the-search-bar.md).
* The **Advanced Search** function, which offers further search methods*.* More about Advanced Search can be found [here](/navigating-and-searching/examples-of-typical-searches/search-functions/advanced-search.md).
