> Today BlockJoinParentQParser creates queries with hardcoded _scoring mode_ "None": 
> {code:borderStyle=solid}
>   protected Query createQuery(Query parentList, Query query) {
>     return new ToParentBlockJoinQuery(query, getFilter(parentList), ScoreMode.None);
>   }
> {code} 
> Analogically BlockJoinChildQParser creates queries with hardcoded _doScores_ "false":
> {code:borderStyle=solid}
>   protected Query createQuery(Query parentListQuery, Query query) {
>     return new ToChildBlockJoinQuery(query, getFilter(parentListQuery), false);
>   }
> {code}
> I propose to have ability to configure this scoring options via query syntax.
> Syntax for parent queries can be like:
> {code:borderStyle=solid}
> {!parent which=type:parent scoreMode=None|Avg|Max|Total}
> {code} 
> For child query:
> {code:borderStyle=solid}
> {!child of=type:parent doScores=true|false}
> {code}
