Performance regression in filters

[mgamanho]

Describe the bug
Performance for filter-based calls is worse now in some cases than it was before moving to partitioned indices.

To Reproduce
Steps to reproduce the behaviour:
Measure time to query in large datasets.

Expected behaviour
Performance for queries should match or exceed that of pre index partitioning versions (14.1.1.0 or 12.2.1.4 currently still use monolithic index contents).
