Hi all, 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:
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 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: 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 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: https://gist.github.com/manisnesan/47685a561605e2229434b38aed11cc65 Have any of you run into this issue? Seems like it could be a bug. Thanks, Michael A. Alcorn
