Subject: Field value feature returning only 0s - LTR feature engineering
Hello everyone,
We are using Solr 8.5 and facing the following issue.
We want to use number of clicks of a documents/page as a feature in LTR model.
We are using in-place updates to set/upload the number of clicks for each
document. When I try to extract features from Solr, all the documents/rows
have values as 0 for clicks feature.
Sample feature
{
"name":"pmetrics_its_nid-ga_metric1-sum",
"class":"org.apache.solr.ltr.feature.FieldValueFeature",
"params":{"field":"pmetrics_its_nid-ga_metric1-sum"},
"store":"_DEFAULT_"
}
Solr Config
<dynamicField name="pmetrics_*" type="pfloat" indexed="false" stored="false"
docValues="true"/>
Am I missing something here ?
Thanks for your answers
Nishanth.
