Summary: Bug in logging efi features
Key: SOLR-16787
URL: https://issues.apache.org/jira/browse/SOLR-16787
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Components: contrib - LTR
Affects Versions: 9.2.1
Reporter: Anna
Efi features are not correctly printed when these conditions persist:
# Asking for logging:
{code:java}
fl=[features format=dense efi.myEfiFeature=2]{code}
# Default feature store used (no feature store passed)
# Asking for reranking:
{code:java}
{!ltr model=my_model efi.myEfiFeature=3}{code}
# Different efis values are passed between logging and reranking:
efi.myEfiFeature=2 vs efi.myEfiFeature=3
The efis logged are computed based on the reranking and not the logging.
Example of response:
{code:java}
"docs": [
{
"id": "41",
"score": 4999.0,
"[features]": "test_efi_0=4996.0,test_efi_1=0.0,efi_feature=3.0"
},
{
"id": "80",
"score": 4955.0,
"[features]": "test_efi_0=4952.0,test_efi_1=0.0,efi_feature=3.0"
},
...{code}
I would expect to have efi_feature=2.0 in this scenario.
This is due to the
*org.apache.solr.ltr.response.transform.LTRFeatureLoggerTransformerFactory.FeatureTransformer#setupRerankingQueriesForLogging*
method, which is not assigning the _transformerExternalFeatureInfo_ parameter
to the
_LTRScoringQuery_ if we have done reranking and the _transformerFeatureStore_
is null (not passed in fl at query time).
