Key: SOLR-10383
URL: https://issues.apache.org/jira/browse/SOLR-10383
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Affects Versions: 6.4.2
Reporter: Vitezslav Zak
Hi,
there is a NPE if I want to debug query in SOLR UI.
I'm using LTR for reranking result.
My features:
{code:json}
{
"initArgs":{},
"initializedOn":"2017-03-29T05:32:52.160Z",
"updatedSinceInit":"2017-03-29T05:56:28.721Z",
"managedList":[
{
"name":"documentRecency",
"class":"org.apache.solr.ltr.feature.SolrFeature",
"params":{"q":"{!func}recip( ms(NOW,initial_release_date), 3.16e-11, 1,
1)"},
"store":"_DEFAULT_"},
{
"name":"niceness",
"class":"org.apache.solr.ltr.feature.SolrFeature",
"params":{"fq":["{!func}recip(niceness, 0.1, 1, 1)"]},
"store":"_DEFAULT_"},
{
"name":"originalScore",
"class":"org.apache.solr.ltr.feature.OriginalScoreFeature",
"params":null,
"store":"_DEFAULT_"}]}
{code}
My model:
{code:json}
{
"initArgs":{},
"initializedOn":"2017-03-29T05:32:52.167Z",
"updatedSinceInit":"2017-03-29T05:54:26.100Z",
"managedList":[{
"name":"myModel",
"class":"org.apache.solr.ltr.model.LinearModel",
"store":"_DEFAULT_",
"features":[
{
"name":"documentRecency",
"norm":{"class":"org.apache.solr.ltr.norm.IdentityNormalizer"}},
{
"name":"niceness",
"norm":{"class":"org.apache.solr.ltr.norm.IdentityNormalizer"}},
{
"name":"originalScore",
"norm":{"class":"org.apache.solr.ltr.norm.IdentityNormalizer"}}],
"params":{"weights":{
"documentRecency":0.1,
"niceness":1.0,
"originalScore":0.5}}}]}
{code}
NPE occurs in this method, where docInfo is null.
{code:title=OriginalScoreFeature.java}
@Override
public float score() throws IOException {
// This is done to improve the speed of feature extraction. Since this
// was already scored in step 1
// we shouldn't need to calc original score again.
final DocInfo docInfo = getDocInfo();
return (docInfo.hasOriginalDocScore() ? docInfo.getOriginalDocScore() :
originalScorer.score());
}
{code}
