Compact dictionary key lookup
<p>Is there a way to write this more compact ?</p>

<pre><code>return _searchRedirectionMap.ContainsKey(query) ? _searchRedirectionMap[query] : "";
</code></pre>

<p>Givent that <code>_searchRedirectionMap</code> is defined as a <code>IDictionary&lt;string,string&gt;</code> </p>
