Solr

Solr is an open-source search platform built on Apache Lucene that helps organize, search, and retrieve large amounts of data efficiently. Think of it as an advanced, digital librarian that indexes websites, documents, or products, so when you enter a query, it quickly finds relevant results. Used by many businesses to power search features, Solr handles complex searches across vast data sets, providing fast, accurate, and customizable results. It's particularly valuable when there's a need for powerful search capabilities within websites, applications, or enterprise systems.
