--------------------------------------------
Summary: 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.
