             Summary: Nodetype index support in Lucene Index
                 Key: OAK-6831
                 URL: https://issues.apache.org/jira/browse/OAK-6831
             Project: Jackrabbit Oak
          Issue Type: Improvement
          Components: lucene
            Reporter: Chetan Mehrotra
            Assignee: Chetan Mehrotra
             Fix For: 1.8


Lucene indexes currently support nodetype index in some form by specifying a property definition for "jcr:primaryType" with propertyIndex=true. However this can cause issue if such rules are mixed with other rules. 

For supporting usecase where same lucene index supports multiple nodetype rules and can be used as pure nodetype index we should have a explicit support for indexing nodetypes.

*Proposal*

Any indexRule would support following properties

* {{nodeTypeIndex}} - Boolean indicating if this rule is for nodetype indexing
* {{sync}} - If nodetype index is sync

if {{nodeTypeIndex}} is enabled then any explicit property definition would be ignored. With this mode following index definition would be safe to use

{noformat}
/oak:index/nodeTypeLucene
  - jcr:primaryType = "oak:QueryIndexDefinition"
  - compatVersion = 2
  - type = "lucene"
  - async = "async"
  + indexRules
    + nt:file
      - nodeTypeIndex = true
    + app:Component
      - nodeTypeIndex = true
{noformat}

Here the rule order would not cause any affect as for any matching rule the nodes primary and mixin types would be indexed
