            <title>[CXX-1045] collection::count() serializes options::count::hint incorrectly</title>
                <link>https://jira.mongodb.org/browse/CXX-1045</link>
                <project id="11980" key="CXX">C++ Driver</project>
                    <description>&lt;p&gt;collection::count() incorrectly serializes the hint object in the count request with a field name of &quot;$hint&quot; instead of &quot;hint&quot;.  When the server receives the incorrect count option &quot;$hint&quot;, it is ignored.&lt;/p&gt;

&lt;p&gt;As a result, passing an options::count object to collection::count which has a hint set will have no effect.&lt;/p&gt;</description>

&lt;p&gt;Message: &lt;a href=&quot;https://jira.mongodb.org/browse/CXX-1045&quot; title=&quot;collection::count() serializes options::count::hint incorrectly&quot; class=&quot;issue-link&quot; data-issue-key=&quot;CXX-1045&quot;&gt;&lt;del&gt;CXX-1045&lt;/del&gt;&lt;/a&gt; collection::count() correctly serialize options::count::hint&lt;/p&gt;

&lt;p&gt;collection::count() was previously using the invalid count command&lt;br/&gt;
option &quot;$hint&quot; to issue hinted count operations.  This commit corrects&lt;br/&gt;
the option name to &quot;hint&quot;.&lt;br/&gt;

&lt;p&gt;Message: &lt;a href=&quot;https://jira.mongodb.org/browse/CXX-1045&quot; title=&quot;collection::count() serializes options::count::hint incorrectly&quot; class=&quot;issue-link&quot; data-issue-key=&quot;CXX-1045&quot;&gt;&lt;del&gt;CXX-1045&lt;/del&gt;&lt;/a&gt; Add hint::to_value(), deprecate hint::to_document()&lt;/p&gt;

&lt;p&gt;The design of hint::to_document() is flawed in that it returns a&lt;br/&gt;
document with a fixed key name of &quot;$hint&quot;, which doesn&apos;t always&lt;br/&gt;
represent the hint option correctly for database operations (commands&lt;br/&gt;
take this option with a key name of &quot;hint&quot;, for example).&lt;/p&gt;

&lt;p&gt;To address this issue, this commit removes knowledge of the key name&lt;br/&gt;
from the hint class, by adding hint::to_value() and deprecating&lt;br/&gt;
hint::to_document().&lt;br/&gt;
