PS Salon

Learn at the cutting edge of Open Source

We are happy to announce that PS Salon will be hosting a series of six online workshops introducing Chorus – an Open Source software toolstack for e-commerce search. Attending these hands-on workshops is your chance to learn with the creators of the open source projects that make up the Chorus toolstack.

In these workshops you will work with the following Chorus components:

  • Solr search engine
  • Querqy – a library for query rewriting
  • SMUI – a UI for search management (‘Searchandizing’)
  • Quepid – a search relevance tuning tool
  • RRE (Rated Ranking Evaluator)
  • Quaerite (Search relevance evaluation and tuning using genetic algorithms) 
  • A search web UI based on Blacklight

Chorus – an Open Source toolstack for e-commerce search

All the components are brought together in the Chorus Docker image: https://github.com/querqy/chorus, you can also see https://querqy.org or read about Chorus on the Open Source Connections blog to find more info about the Chorus initiative.

This is the first run of these workshops and we are offering 16 free places to interested attendees. This is a great one time opportunity to receive free hands on training with the creators of Chorus as we will be charging for future courses. If you are interested in attending these workshops please apply for a place below. We are looking for people who will be a good fit for the course, are able to attend all six workshops, and will provide feedback on the course following completion.


This is a fast paced workshop for people who have been doing search, and want to learn the latest in open source offerings, so we expect you to already have familiarity with search in general, and exposure to either Solr or Elasticsearch platforms. We do NOT expect you to have any familiarity with any of the other components of Chorus, we’ll teach you that! If you aren’t familiar with search, we recommend any of the intro to Solr classes, as well as the Think Like a Relevancy Engineer course offered by OpenSource Connections. We are looking for interested people who are focused on optimizing e-commerce (or an adjacent field) search.
