Currently the MoreLikeThis is a giant monolithic class, difficult to maintain.
Scope of this issue is to refactor the code, separating responsibilities of the
main components and funcitonality :
- *MoreLikeThis facade* - the entry point
- *MoreLikeThisParams* - the huge set of params and defaults provided for the
More Like This
- *Interesting Terms Retriever* - given a document in input this component has
the responsibility of identifying interesting terms
- *Term Scorer* - given a term with document stats and collection stats, this
module has the responsibility to score the term
- *Query Builder* - given a set of params and interesting terms, this component
has the responsibility to build the Lucene query
