Extension to MoreLikeThis to use tag information
------------------------------------------------
Key: LUCENE-1910
URL: https://issues.apache.org/jira/browse/LUCENE-1910
Project: Lucene - Java
Issue Type: New Feature
Components: contrib/*
Reporter: Thomas D'Silva
I would like to contribute a class based on the MoreLikeThis class in
contrib/queries that generates a query based on the tags associated
with a document. The class assumes that documents are tagged with a
set of tags (which are stored in the index in a seperate Field). The
class determines the top document terms associated with a given tag
using the information gain metric.
While generating a MoreLikeThis query for a document the tags
associated with document are used to determine the terms in the query.
This class is useful for finding similar documents to a document that
does not have many relevant terms but was tagged.
