> Aggregate logic in oak-lucene currently tries to apply matcher on each of the child node of a modified parent node. This is required for those case where pattern involves wild card like aggregating '\*/\*/\*' pattern.
> However this performs poorly if the aggregate does not involve pattern. For e.g. if we have defined a property definition for 'jcr:content/@status' for nt:base
> {noformat}
>   + indexRules 
>    + nt:base 
>     + properties 
>      + status 
>       - name = "jcr:content/status"
>       - propertyIndex = true
> {noformat}
> For above definition current logic would try to apply the matcher for 'jcr:content' on each of the child nodes. So if we have a folder have 1000 entries it would read that many child nodes. 
> As a fix we should check if the aggregate path has wild card or not. if its specific then aggregate logic should directly lookup child with given name
