Welcome to Querqy.org!¶
Querqy.org is an umbrella for open source tools and libraries that helps you create a powerful e-commerce search platform quickly. The focus is on optimising search relevance from day one, beyond the out-of-the-box capabilities of the Solr and Elasticsearch search engines.
- Documentation (incl. a ‘Getting started’)
- Source code
Make sure you check out Chorus and fire up a Docker Compose for an e-commerce search application that demonstrates Solr, Querqy, SMUI, RRE, Quepid and a Blacklight search UI working together.
