Subject Re: Solr learning to rank features question
Date Tue, 29 Aug 2017 19:10:04 GMT
Thank you Diego! This works with some small changes. My feature ended up
looking like this:

{
  "name" : "FeatureA",
  "store" : "commonFeatureStore",
  "class" : "org.apache.solr.ltr.feature.SolrFeature",
  "params" : {
    "q" : "{!func}if(gt(ms(CutoffDate,NOW),0),exists(query({!v=
PreZones:${zone}})),exists(query({!v=PostZones:${zone}})))"
  }
},
