Numeric Range Indexing And Range Query Filtering

via “numeric range queries and aggregations”

A query and indexing engine for Redis, providing secondary indexing, full-text search, vector similarity search and aggregations.

Unique: Uses a specialized numeric range tree (not a B-tree or skip list) optimized for Redis' in-memory model, combined with aggregation pipeline that supports expression evaluation (src/result_processor.h) for computed fields during aggregation, enabling complex numeric transformations without post-processing

vs others: Faster than SQL databases for numeric range queries on indexed fields because the range tree is optimized for in-memory traversal; more flexible than simple hash-based filtering because it supports arbitrary range bounds without pre-computed buckets
