Frequent deletion and in-place update in incremental filtered-vector indexes
Develop support for frequent deletion and in-place update in the WoW fully incremental insert-from-empty filtered-vector index while preserving its dynamic range-search functionality.
References
More recent work makes the filtered index mutable: Dynamic RFANNS, DIGRA, and RangePQ address changing data, while WoW is a fully incremental insert-from-empty design but leaves frequent deletion and in-place update as open concerns.

This work considers a static dataset, and how to efficiently deal with dynamic data (i.e., vector insertions and deletions) is an open problem.
