            <title>[SERVER-40691] $nin:[[],...] queries are not indexed</title>
                <link>https://jira.mongodb.org/browse/SERVER-40691</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Since v4.0.9, &lt;tt&gt;$nin&lt;/tt&gt; queries containing arrays are no longer possible when the &lt;tt&gt;notablescan&lt;/tt&gt; setting is enabled on the server. The server will always throw a &quot;No query solutions&quot; error, due to &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-38949&quot; title=&quot;Incorrect index bounds for {$ne: [&amp;quot;String&amp;quot;]} query&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-38949&quot;&gt;&lt;del&gt;SERVER-38949&lt;/del&gt;&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;Since v4.0.9, &lt;tt&gt;$nin&lt;/tt&gt; queries are no longer possible when the &lt;tt&gt;notablescan&lt;/tt&gt; setting is enabled on the server. The server will always throw a &quot;No query solutions&quot; error, because indexes made for the fields being queried are not respected for a &lt;tt&gt;$nin&lt;/tt&gt; query, resulting in a full-table scan and the error. This is most likely due to &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-38949&quot; title=&quot;Incorrect index bounds for {$ne: [&amp;quot;String&amp;quot;]} query&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-38949&quot;&gt;&lt;del&gt;SERVER-38949&lt;/del&gt;&lt;/a&gt;&lt;/p&gt;

This ticket should be to consider whether it makes sense to do that.&lt;/p&gt;

&lt;p/&gt;
&lt;div id=&quot;syntaxplugin&quot; class=&quot;syntaxplugin&quot; style=&quot;border: 1px dashed #bbb; border-radius: 5px !important; overflow: auto; max-height: 30em;&quot;&gt;
&lt;table cellspacing=&quot;0&quot; cellpadding=&quot;0&quot; border=&quot;0&quot; width=&quot;100%&quot; style=&quot;font-size: 1em; line-height: 1.4em !important; font-weight: normal; font-style: normal; color: black;&quot;&gt;
		&lt;tbody &gt;
				&lt;tr id=&quot;syntaxplugin_code_and_gutter&quot;&gt;
						&lt;td  style=&quot; line-height: 1.4em !important; padding: 0em; vertical-align: top;&quot;&gt;
					&lt;pre style=&quot;font-size: 1em; margin: 0 10px;  margin-top: 10px;   margin-bottom: 10px;  width: auto; padding: 0;&quot;&gt;&lt;span style=&quot;color: black; font-family: &apos;Consolas&apos;, &apos;Bitstream Vera Sans Mono&apos;, &apos;Courier New&apos;, Courier, monospace !important;&quot;&gt;{$and:[{a:{$ne:null}},{a:{$ne:[]}}]}&lt;/span&gt;&lt;/pre&gt;
			&lt;/td&gt;
		&lt;/tr&gt;
			&lt;/tbody&gt;
&lt;/table&gt;

This is due to the index prohibition on &lt;tt&gt;$ne:[&lt;span class=&quot;error&quot;&gt;&amp;#91;any&amp;#93;&lt;/span&gt;]&lt;/tt&gt;.&lt;/p&gt;</comment>
                            <comment id="2217242" author="asya" created="Wed, 17 Apr 2019 22:24:43 +0000"  >&lt;p&gt;&lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=tubbo&quot; class=&quot;user-hover&quot; rel=&quot;tubbo&quot;&gt;tubbo&lt;/a&gt; can you provide the actual document and query you are using?&lt;/p&gt;

&lt;p&gt;The bug you reference fixed a correctness problem, so if this is causing an issue for you, it may be that you were already not getting correct results, and therefore might need to rewrite the query.&lt;/p&gt;</comment>
                            <comment id="2216874" author="eric.sedor" created="Wed, 17 Apr 2019 18:37:01 +0000"  >&lt;p&gt;Thanks for the added step, &lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=tubbo&quot; class=&quot;user-hover&quot; rel=&quot;tubbo&quot;&gt;tubbo&lt;/a&gt;; An outright exception for &lt;tt&gt;$nin&lt;/tt&gt; may be unlikely, as the purpose of &lt;tt&gt;notablescan&lt;/tt&gt; is to protect against the possible impact of unindexed queries.&lt;/p&gt;

&lt;p&gt;One potential workaround is to contrive a query on a compound index (e.g., query for {&lt;tt&gt;a:&amp;lt;val&amp;gt;,b:{ $nin: [[], null]&lt;/tt&gt;}} with the goal of using index {&lt;tt&gt;a:1,b:1&lt;/tt&gt;}).&lt;/p&gt;

&lt;p&gt;I am looking into the permanence of the index ban on &lt;tt&gt;$nin&lt;/tt&gt;.&lt;/p&gt;</comment>
