FunctionQuery returns the *value* of a field (or a function of it) as the value for a query - it does not use Similarity at all. If you put a FunctionQuery in a BooleanQuery with other queries (like normal relevance queries), the scores will be added together. If you use a BoostedQuery, the FunctionQuery score will be multiplied by the normal relevance score. -Yonik
