Description
Adds a "Comparisons with null" section to Expressions: comparing lists and maps that hold
nullnow returnsnull, andIN, index lookups, joins andDISTINCTfollow the same rule. Thenullparagraph in the CASE section now links to it.Product PR
memgraph/memgraph#4794
Checklist
featureorbugfixlabel addedLeft out: the changed plan cost estimate for such filters (internal). The release note doesn't mention that index lookups, relationship property scans and joins now match nothing for a value holding
null; it could add one line.Noticed, not fixed: the WHERE clause page has the heading "1.2. Inequality Operators Operators", and the collections page says "comberable".
