Solr learning to rank features question

Hello,

I have a somewhat complex solr filter query that I am hoping to turn into a
feature for learning to rank, but I am not sure if it's possible. I would
like to OR two fq together for one of my features. I have a cutoff date and
I need to check one field if NOW is before the cutoff, and a different
field if NOW is after the cutoff. Is this possible?

Something to the effect of this:
{
  "name" : "FeatureA",
  "store" : "commonFeatureStore",
  "class" : "org.apache.solr.ltr.feature.SolrFeature",
  "params" : {
    "fq" : [
      "{!frange l=NOW}CutOffDate",
      "{!term f=PreCutOffZones}${zone}"
    ]
    OR
    "fq" : [
      "{!frange u=NOW}CutOffDate",
      "{!term f=PostCutOffZones}${zone}"
    ]
  }
},

Thank you!

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}})))"
  }
},

Hi Brian,

The plugin doesn't allow you to express multiple function queries in the
same feature. Maybe in this case you can express both the tw queries in one
unique function query, using the if function.

Something like:

"fq":"if(gt(ms(NOW,mydatefield),0,query(PreCutOffZones:${zone}), query(
PostCutOffZones:${zone}))"


(Function query documentation here:
https://cwiki.apache.org/confluence/display/solr/Function+Queries)

Let me know if it works.

Cheers,
Diego
