Definition
A distributed, RESTful search engine built on Apache Lucene that functions as a hybrid vector store in RAG pipelines; it excels at combining lexical keyword matching (BM25) with dense vector search (k-NN) to maximize retrieval precision. While highly scalable and feature-rich, it introduces more operational complexity and resource overhead compared to specialized, cloud-native vector databases.
Shift from ELK-stack log analysis to hybrid vector retrieval for generative AI context.
"A massive industrial library that uses both high-precision GPS coordinates to locate thematic clusters and a traditional alphabetical card catalog for exact word matches."
