Hi,
I have configured LTR in my solr collection and I am able to see my feature and
model file. To test things out I have kept only two features and a very basic
model file. I have attached both the files.
I am able to retrieve the features using the following query :
localhost:8983/solr/waterstest/query?q=*:*&fl=title,id,description,score,[features
store=myWatersFeatureStore efi.boostedTitle=columns
efi.boostedDescription=Heater]<http://localhost:8983/solr/waterstest/query?q=*:*&fl=title,id,description,score,%5bfeatures%20store=myWatersFeatureStore%20efi.boostedTitle=columns%20efi.boostedDescription=Heater%5d>
The above works fine. I am able to retrieve the feature and the score with the
data
The problem comes when I try to rerank the results with the uploaded model.
Here are the queries I have tried to rerank the results
localhost:8983/solr/waterstest/query?q=title:columns&rq={!ltr
model=myWatersModel reRankDocs=100 efi.boostedTitle=columns
efi.boostedDescription=Heater}&fl=id,score<http://localhost:8983/solr/waterstest/query?q=title:columns&rq=%7b!ltr%20model=myWatersModel%20reRankDocs=100%20efi.boostedTitle=columns%20efi.boostedDescription=Heater%7d&fl=id,score>
Response
{
"responseHeader":{
"zkConnected":true,
"status":400,
"QTime":28,
"params":{
"q":"title:columns",
"fl":"id,score",
"rq":"{!ltr model=myWatersModel reRankDocs=100 efi.boostedTitle=columns
efi.boostedDescription=Heater}"}},
"error":{
"metadata":[
"error-class","org.apache.solr.common.SolrException",

"root-error-class","org.apache.solr.client.solrj.impl.BaseHttpSolrClient$RemoteSolrException"],
"msg":"Error from server at null: cannot find model myWatersModel",
"code":400}}
There is nothing in logs just the same error there
org.apache.solr.client.solrj.impl.BaseHttpSolrClient$RemoteSolrException: Error

I am able to retrieve the model store also :
localhost:8983/solr/waterstest/schema/model-store<http://localhost:8983/solr/waterstest/schema/model-store>
{
"responseHeader":{
"status":0,
"QTime":1},
"models":[{
"name":"myWatersModel",
"class":"org.apache.solr.ltr.model.LinearModel",
"store":"myWatersFeatureStore",
"features":[{
"name":"isboostedTitle",
"norm":{"class":"org.apache.solr.ltr.norm.IdentityNormalizer"}},
{
"name":"isboostedDescription",
"norm":{"class":"org.apache.solr.ltr.norm.IdentityNormalizer"}}],
"params":{"weights":{
"isboostedTitle":0.4,
"isboostedDescription":0.2}}}]}
If the feature query works and I am able to retrieve the model as well then why
am I getting the model null error. I know the error handling part is not apt
here so can someone help me to point out what all could have gone wrong here?
Thanks and Regards
