Changes proposed

Adds a new, technical, practitioner-led article to the Kubesimplify blog focusing on hybrid retrieval architectures in local RAG systems.

  • New: content/blog/sqlite-fts5-dense-hybrid-retrieval.md — Deep-dive into sparse vs. dense search limitations, SQLite FTS5 BM25 configurations, Reciprocal Rank Fusion (RRF), deterministic domain reranking, and vector cache memory footprints.
  • New: public/img/blog/sqlite-fts5-dense-hybrid-retrieval/ — Static assets (architecture diagrams, benchmarks, UI screenshots).
  • Modified: content/authors.json — Add author profile entry for ishwar.
  • New: public/img/authors/ishwar.jpg — Author avatar placeholder.

No other changes are made to the site's code.

Note to reviewers

This post focuses on systems-level search engineering and database schemas (SQLite), which is well-suited for KubeSimplify's backend, cloud-native, and infrastructure audience.
