Emmanuel Lecharny commented on DIRSERVER-1808:
----------------------------------------------
The (ObjectClass=*) node is now removed from the filter : it's useless.
> We should evaluate the Scope and any other index in a fliter only when the #
> of candidate is above a threshold

> Key: DIRSERVER-1808
> URL: https://issues.apache.org/jira/browse/DIRSERVER-1808
> Project: Directory ApacheDS
> Issue Type: Improvement
> Affects Versions: 2.0.0-M10
> Reporter: Emmanuel Lecharny
> Fix For: 2.0.0-M11
>
>
> Currently, we evaluate *all* the nodes in a filter, regardless to the result
> of previous evaluation. It makes no sense to evaluate some & node if one node
> evaluates to 0 or 1. It makes no sense to evaluate some following nodes of a
> | node if one node evaluate to MAX.
> We could probably save a few CPU this way.
