                <link>https://jira.mongodb.org/browse/DOCS-16615</link>
                <project id="10380" key="DOCS">Documentation</project>
                    <description>&lt;p&gt;Dear all,&lt;/p&gt;

&lt;p&gt;Our documentation is proving inconsistent/contradictory &#160;information regarding `$regex` operator and case-insensitive indexes:&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;&lt;a href=&quot;https://www.mongodb.com/docs/manual/reference/operator/query/regex/#:~:text=Case%20insensitive%20regular%20expression%20queries%20generally%20cannot%20use%20indexes%20effectively.%20The%20%24regex%20implementation%20is%20not%20collation%2Daware%20and%20is%20unable%20to%20utilize%20case%2Dinsensitive%20indexes.&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;One&lt;/a&gt;: Case insensitive regular expression queries generally cannot use indexes effectively. The &lt;tt&gt;$regex&lt;/tt&gt;&#160;implementation is not collation-aware and is&#160;&lt;b&gt;unable to utilize case-insensitive indexes.&lt;/b&gt;&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;&lt;a href=&quot;https://www.mongodb.com/docs/atlas/schema-suggestions/case-insensitive-regex/#avoid-inefficient-regex-matching:~:text=If%20you%20frequently,and%20accent%20marks.&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;Two:&lt;/a&gt;&#160; &#160;If you frequently run &lt;b&gt;case-insensitive regex queries (utilizing the &lt;tt&gt;i&lt;/tt&gt;&#160;option), .....Alternatively, you can create a&#160;&lt;a href=&quot;https://www.mongodb.com/docs/manual/core/index-case-insensitive/&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;case-insensitive index&lt;/a&gt;&#160;to support your queries&lt;/b&gt;.* You can also specify a &lt;a href=&quot;https://www.mongodb.com/docs/manual/reference/collation/&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;collation&lt;/a&gt;&#160;on an index to define language-specific rules for string comparison, such as rules for lettercase and accent marks.&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;Thank you in advance for taking time and fixing this.&lt;/p&gt;

&lt;p&gt;Friendly regards,&lt;/p&gt;

&lt;p&gt;Marina.&lt;/p&gt;</description>
