--------------------------------------------
Hi,
Is there any idea when this patch will be included in Solr Code Base ?
I find it to be a very interesting aspect to complete the Join feature!
Cheers
> Support scoreMode parameter for BlockJoinParentQParser
> ------------------------------------------------------

> 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}
