The Intermediate and Advanced Solr Training went very well. A few of the things I liked:
— The intermediate and advanced command files included in the training material were very helpful. I’m still referring to them after taking the class as I look more in-depth into the various features.
— The provided example data and scripts to load the data into Solr are another big time saver. Also, this gives me something to refer to as I review the training notes.
— The hands-on exercise/labs
The training covered several Solr features e.g., streaming aggregation, JSON API, etc. that we haven’t really used yet, but may be very useful to us in the future.

The CORE training made the complex concepts around solr easy to understand. Although it was a group setting, I still feel like I received individual attention. All of my questions were answered well, and at the close of each unit, I felt confident in my understanding.
