Our brand new online course-series "PS salon" kicks off in collaboration with Chorus!

We are happy to announce that our brand new online course-series PS salon kicks off in collaboration with Chorus!

Following the great success and demand of the Open Source tool stack presentation by René Kriegler,Eric Pugh, Paul Bartusch and Johannes Peter at this year’s online edition of Berlin Buzzwords (in co-presentation with Haystack the search relevance conference, and MICES the e-commerce search event) we are bringing you Chorus, an intensive hands-on workshop in six parts.

Chorus workshops

Attending these workshops is your chance to learn with the creators of the open source projects that make up the Chorus toolstack.

Who can benefit from these Chorus workshops?

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.  


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 trialing with the creators of Chorus as we will be charging for future courses. If you are interested in attending these workshops please visit the PS Salon website where you can find more details and apply. Places will be awarded following an application. 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.
