Michael A. Alcorn updated SOLR-11386:
-------------------------------------
Description:
I'm getting some extremely strange behavior when trying to extract features for
a learning to rank model. The following query incorrectly says all features
have zero values:
{code}
http://gss-test-fusion.usersys.redhat.com:8983/solr/access/query?q=added couple
of fiber channel&rq={!ltr model=redhat_efi_model reRankDocs=1
efi.case_summary=the efi.case_description=added couple of fiber channel
efi.case_issue=the efi.case_environment=the}&fl=id,score,[features]&rows=10
{code}
But this query, which simply moves the word "added" from the front of the
provided text to the back, properly fills in the feature values:
{code}
http://gss-test-fusion.usersys.redhat.com:8983/solr/access/query?q=couple of
fiber channel added&rq={!ltr model=redhat_efi_model reRankDocs=1
efi.case_summary=the efi.case_description=couple of fiber channel added
efi.case_issue=the efi.case_environment=the}&fl=id,score,[features]&rows=10
{code}
The explain output for the failing query can be found here:
https://gist.github.com/manisnesan/18a8f1804f29b1b62ebfae1211f38cc4
and the explain output for the properly functioning query can be found here:
