Apache Solr is an open-source search platform built on Lucene that delivers sub-second full-text search and real-time analytics for massive datasets.

Solr powers search for giants like Adobe, Verizon, and AT&T by leveraging the Lucene library for high-performance indexing. It handles petabytes of data across distributed clusters (SolrCloud) using a REST-like API to manage JSON, XML, and CSV documents. Key features include faceted navigation, hit highlighting, and advanced spatial search (geospatial filtering). Because it runs in a Java servlet container like Jetty, deployment is straightforward and scales horizontally to meet high-traffic demands.

## Recent Public Talks and Demos

### [Más allá del RAG: Grafos universales para datos no universales](https://santiago.aitinkerers.org/talks/rsvp_Ic5kPKxkc3I)

Hoy, la mayoría de los sistemas de information retrieval usan arquitecturas tipo RAG o GraphRAG: se basan en búsqueda semántica, embeddings y modelos de lenguaje para recuperar información relevante.

### [Covariate Search](https://hong-kong.aitinkerers.org/talks/rsvp_bHTSKW0CfRo)

The first practical application of covariate search (with the potential of revolutionizing the search industry) by introducing a new modality. In the demo I am showcasing how we can vectorize a set of keywords semantically and perform a search on other sets (this is not currently possible with semantic search).
