Description

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: tableName:code

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.
