Subject [jira] [Updated] (SOLR-5882) Introduce score local parameter for {!parent} query parser
Date Sun, 02 Aug 2015 20:46:05 GMT

     [ https://issues.apache.org/jira/browse/SOLR-5882?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Mikhail Khludnev updated SOLR-5882:
-----------------------------------
    Attachment: SOLR-5882.patch

attaching patch.
* introduce \{!parent score=..}
* it turns out, \{!child} already returns scores always
* introduced util for parsing score enum, it also made query-time join parser more correct,
it throws {{SolrException}} on wrong enum name.
* fix ScoreMode.Min at ToParentBlockJoin and test it

I'm kindly ask to review. Due to the last item, I want to commit it before 5.3 cut.

> 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}
