Goal of this issue is to make our search bar more accessible.

Ideas

To make search bar more usable by users with disabilities:

• add a text label attribute for the search box that is the same as the existing tooltip, so this text label is read by the screen reader
• maybe we could tell browser/user that search results are displayed below the search box
• Maybe the auto suggest search results could use the same tabindex as the search field, so it's easy to tab through
• maybe we can research online the best practises for building an accessible search box
