Feature: Refresh cache
</h2>
<p style={{ color: '#182359', font: 'open sans' }}>
Adding the refresh prop to your InstantSearch component gives you
the possibility to refresh the cache.

How to test it?
</h3>
<div style={{ color: '#182359', font: 'open sans' }}>
By default, the 'refresh' prop is disabled. You will need
to open your network tab in the developer tools.
<ol>
<li>
Type a query in the SearchBox (for instance
'cellphones'). You should see 10 requests to Algolia
(one per letter)
</li>
<li>
Type 'cellphones' again, you will see that no
additional query is made since the results are retrieved from
the cache
</li>
<li>
Make sure the SearchBox is empty, click on the 'Refresh
cache' button (you should see that Refresh set to true in
the info box below the SearchBox)
</li>
<li>
Type your previous query again: the cache has been cleared and
you will see new requests made to Algolia
</li>
</ol>
</div>
