I have a test Solr environment using Carrot2 on Ubuntu. With the Carrot2 workbench I can alternate between the three defined algorithms (Lingo, STC, kmeans). How do I do the same thing in the Solr admin query tool? is it an argument passed with the clustering parameter?

All 3 algorithms are defined in the solrconfig.xml, which is by and large a copy of the example from collection1. I'm inferring it is using Lingo by default but not sure where to switch it to STC if I'd like.

You can use the clustering.engine parameter to select the clustering engine at query time. To cluster the results with STC, add clustering.engine=stc to your request. In Solr Admin, you can pass the extra parameter in the Raw Query Parameters field of the query screen. You may also need to change the default Request-Handler to the one that has results clustering enabled.
