Hi, I want to use this plugin with Solr 9, I tried to change the code but I could not solve the errors which occurred after changing the POM.xml file. Can you guide me how can I upgrade this for Solr 9. Regards
I took at stab at upgrading to Solr 7 (master...garysieling:Solr.7.0.0).
I'm stuck on a change that removes "getBoost" and "setBoost", and was wondering if you had any insight on what the right change would be.
Here is the ticket which appears to have made this change:

Hi Simon,
I recently watched a video of the "Personalized Search and Job Recommendations" talk you did at Revolution 2017 and decided to try out the unsupervised feedback plugin. I seem to be running into some issues, though.
I've configured an UnsupervisedFeedbackHandler based on the example config you have (modified as needed), but the handler is throwing a 500 error.
I have a fresh Solr 6.3 instance with some dummy data (just id and text fields). Any insight into what could be going on would be greatly appreciated.
See stack trace below:
