/**
* The SearchBar component should be the primary search input for the app. It should be
* located near the top of the screen, below the [TopBar](#/top-bar).
*
* ```html
*
*
* ```
*
* ## Use With NgModel
* The search query can be bound with `NgModel`, which can be useful for implementing a reset function:
*
* ```html
*
*
* ```
*
* ## Content Projection
* Content inside the `` tags will be projected inside the component, to the left of the
* search bar. This can be used, for example, to display current filters being applied to the search.
*
* ```html
*
* Tag 1close
*
* ```
*
* ## Custom Icons
* Icons in the `` can be replaced with custom ones.
*
* ```html
*
*
* ```
