> While trying to create a model definition, I was getting back the response:
> {code}
> {
>   "responseHeader":{
>   [...]
>   "error":{
>     [...]
>     "msg":"org.apache.solr.ltr.model.ModelException: Model type does not exist org.apache.solr.ltr.model.LinearModel",
>     "code":400}
>     }
> }
> {code}
> I initially thought this was related to the library, but after a while figured out that I had forgotten to create a feature in my feature store. After creating that the model was created as expected. 
> To recreate this:
> {code}
> curl -XPOST -H 'Content-Type: application/json' \
> -d '{
>   "store" : "myStore",
>   "name" : "myModel",
>   "class" : "org.apache.solr.ltr.model.LinearModel",
>   "features" : [{
>     "name" : "nonExistentFeature"
>   }],
>   "params" : {
>     "nonExistentFeature" : 1.0
>   }
> }' http://localhost:8983/solr/$CORE/schema/model-store
