Building features in solr

2018-06-03 Thread Roee T 
Hi all,

I am trying to compute feature values for some features.
i need some examples on how to form the following features in the feature
file and if needed in the URL:

1. number of overlapping terms between the query and another field (the
document).
2. query likelihood probability.
3. maximum number of terms in order. 

any help would be appreciated 

thank you

Hi all,
I'm trying to upload the most simple model to solr 7.3.1 and i get an error:

the model:

{
   "class" : "org.apache.solr.ltr.model.MultipleAdditiveTreesModel",
   "name" : "my",
   "features":[],
   "params" : {
   "trees" : [
   {
   "weight" : 1,
   "root" : {
   "value" : -10
   }} ]}}
   
The error:
  "error":{
"metadata":[
  "error-class","org.apache.solr.common.SolrException",
  "root-error-class","java.lang.IllegalArgumentException"],
"msg":"org.apache.solr.ltr.model.ModelException: Model type does not
exist org.apache.solr.ltr.model.MultipleAdditiveTreesModel",
"code":400}}


I inserted the configurations to solrconfig.xml like

please help me 
Thanks you all ;)

Thank you so much all of you

curl -X PUT -H "Content-Type: application/json" -d "@Myfeatures.json"
"http://localhost:8983/solr/techproducts/schema/feature-store;
