Boolean field queries fail on Redis 8

[abrookins]

Problem

Boolean field queries return incorrect results on Redis 8, ignoring the boolean filter entirely. The same queries work correctly on Redis 7.4.x.

Example

filter_expression = (MyModel.flag == False)
query = MyModel.find(filter_expression).sort_by("-created_at")
# On Redis 8: Returns ALL records including flag=True
# On Redis 7.4: Correctly filters to only flag=False records

Impact

This is a major compatibility issue for users on Redis 8 (released May 2025).

• Querying over indexed bool fields fails on Redis 8, results ignore boolean expression (but it works well/as expected with Redis 7.4.x) #712 (original user report)

Investigation Needed

• Determine if Redis 8 changed boolean indexing behavior
• Check if our TAG-based boolean indexing needs adjustment for Redis 8
• May need to test with different boolean storage formats
