-----------------------------------
Summary: Failure to execute query when solr index contains
documents with different fields
Key: MAHOUT-1633
URL: https://issues.apache.org/jira/browse/MAHOUT-1633
Project: Mahout
Issue Type: Bug
Components: CLI
Affects Versions: 1.0
Environment: CentOS 6.5
Reporter: Tom Lampert
Priority: Critical
Fix For: 1.0
When using Lucene2Seq on a lucene Index that contains documents that have
different fields the following error is output:
java.lang.IllegalArgumentException: Could not create query scorer for query:

The query that is used executes fine in Solr upon the same index. If the index
does not contain documents having different fields (from the same source) the
function executes without a problem.
