Alan Woodward commented on LUCENE-7722:
---------------------------------------
Looking closer at BoostingQuery, I think the same effect could be had by using
a BooleanQuery and wrapping the 'suppressing' subquery with a negative-valued
BoostQuery? In addition, BoostingQuery has no tests that actually run the
query...
On reader-dependent DoubleValuesSource implementations, I think we need to add
something like a rewrite() function to make the dependancy explicit. Otherwise
you could have odd interactions with things like the QueryCache.

> We already have FunctionScoreQuery, which is more flexible than BoostedQuery
> as it can combine scores in arbitrary ways and only requests scores on the
> underlying scorer if they are needed. So let's remove BoostedQuery?
