Subject [jira] [Updated] (SOLR-5882) Introduce score local parameter for {!parent} query parser
Date Mon, 03 Aug 2015 07:14:06 GMT

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

Mikhail Khludnev updated SOLR-5882:
-----------------------------------
    Description: 
I propose to have ability to configure scoring mode by local parameter

Syntax for parent queries can be like:

{code:borderStyle=solid}
{!parent which=type:parent score=None|Avg|Max|Total|Min}...
loweracase is also accepted
{code} 

Child query enables scoring by default.



  was:
*TODO* it needs to be updated.

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}
