Uwe Schindler commented on SOLR-7912:
-------------------------------------

The score of a MLT query should not be changed by additional clauses like the 
one to exclude original document. The coordination factor changes the score of 
a query depending on how many clauses are in a boolean query. This problem does 
not really affect the query here because it is a combination of must/must_not, 
but it should still be done.

> Add support for boost and exclude the queried document id in MoreLikeThis
