> After LUCENE-8099, the "BoostedQuery" is deprecated by the use of the 
> "FunctionScoreQuery". With the BoostedQuery, it was possible to access at its 
> underlying "valueSource". But it is not the case with the class 
> "FunctionScoreQuery". It has got only a getter for the wrapped query,  
> For development of specific parsers, it would be necessary to access the 
> valueSource of a "FunctionScoreQuery". I suggest to add a new getter into the 
> class "FunctionScoreQuery" like below:
> {code:java}
>  /**
>    * @return the wrapped Query
>    */
>   public Query getWrappedQuery() {
>     return in;
>   }
>  /**
>    * @return the a source of scores
>    */
>   public DoubleValuesSource getValueSource() {
>     return source;
>   }
> {code}
