Search offers users a way to explore a website or application using keywords. Search can be used as the primary means of discovering content, or as a filter to aid the user in finding content.
The Search Field follows the same basic design principles as the Input Fields.
On a landing or home page, it is recommended that the search box be placed in the top right area of the screen. This is where users expect to find the search.
On a search results page, the natural position of the searchbox is closer to the search results. This helps indicate a relationship between the results and the search query.
You can also use a larger version of the search field.
