            <title>[SERVER-73242] Partial index with $geoWithin filter crashes when querying a big polygon document</title>
                <link>https://jira.mongodb.org/browse/SERVER-73242</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;jstest to reproduce the issue is attached.&lt;/p&gt;

&lt;p&gt;Imagine we create an index with partial filter expression {location: $geoWithin: &amp;lt;polygonA&amp;gt;}.&lt;br/&gt;
And query the collection with filter {location: $getWithin: &amp;lt;polygonB&amp;gt;}.&lt;/p&gt;

&lt;p&gt;During planning, isSubsetOf(index filter expression, query expression) will be called to determine if index can be used.&lt;/p&gt;

&lt;p&gt;It will check if polygonB is inside polygonA: &lt;a href=&quot;https://github.com/mongodb/mongo/blob/04299d14a33a89023b6bc69d8d59a618aa603e5d/src/mongo/db/matcher/expression_algo.cpp#L750&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://github.com/mongodb/mongo/blob/04299d14a33a89023b6bc69d8d59a618aa603e5d/src/mongo/db/matcher/expression_algo.cpp#L750&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;GeoMatchExpression::matchesGeoContainer has an explicit check to never match big polygon, which fails for some reason&lt;br/&gt;
&lt;a href=&quot;https://github.com/mongodb/mongo/blob/04299d14a33a89023b6bc69d8d59a618aa603e5d/src/mongo/db/matcher/expression_geo.cpp#L415&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://github.com/mongodb/mongo/blob/04299d14a33a89023b6bc69d8d59a618aa603e5d/src/mongo/db/matcher/expression_geo.cpp#L415&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;And GeometryContainer::contains is called that fails if the other container is a big polygon:&lt;br/&gt;
&lt;a href=&quot;https://github.com/mongodb/mongo/blob/04299d14a33a89023b6bc69d8d59a618aa603e5d/src/mongo/db/geo/geometry_container.cpp#L322&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://github.com/mongodb/mongo/blob/04299d14a33a89023b6bc69d8d59a618aa603e5d/src/mongo/db/geo/geometry_container.cpp#L322&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;It looks like the bug can be triggered easier by just inserting a document with big polygon and querying if it is within another geometry, but for some reason, the only way this actually breaks in partial index filter.&lt;/p&gt;</description>
