Modern search workloads increasingly blend text retrieval with aggregations, vector search, and real-time analytics, pushing traditional inverted-index architectures beyond their original design. This session examines how techniques from columnar databases and high-performance analytics engines are being adopted to meet these demands.

We explore three key shifts: how columnar storage improves cache locality for efficient aggregation and filtering; how SIMD and vectorized computation accelerate scoring, filtering, and similarity operations on modern CPUs; and how bulk ingestion and execution pipelines reduce coordination overhead while maximizing hardware utilization.

Drawing from evolving open-source search ecosystems and real-world engineering efforts, we analyze where row-oriented execution falls short, discuss hybrid models combining inverted indexes with columnar processing, and explore treating search queries as vectorized data pipelines.

Targeting developers and researchers interested in search internals, distributed systems performance, and the retrieval-analytics intersection, attendees will gain practical understanding of how hardware-aware design influences search architecture today, the trade-offs of integrating columnar and vectorized execution into retrieval systems, and where search infrastructure is heading next.
