* <h2>Index Time Boost</h2>
* <p>
* When indexing, a boost value can either be associated on the document level,
* or per field. The match all query does not take boosting into account by
* default. In order to take boosting into account, the <code>norms_field</code>
* needs to be provided in order to explicitly specify which field the boosting
* will be done on (Note, this will result in slower execution time). For
* example:
* </p>
*
* <pre class="prettyprint lang-js">
* <span class="pun">{</span><span class="pln"><br> </span><span class="str">"match_all"</span><span class="pln"> </span><span class="pun">:</span><span class="pln"> </span><span class="pun">{</span><span class="pln"> </span><span class="str">"norms_field"</span><span class="pln"> </span><span class="pun">:</span><span class="pln"> </span><span class="str">"my_field"</span><span class="pln"> </span><span class="pun">}</span><span class="pln"><br></span><span class="pun">}</span>
