[jira] [Created] (DIRSERVER-2276) Index like (&(modifyTimestamp>=20190429000000Z)(modifyTimestamp<=20190430000000Z)) should be fast

Emmanuel Lecharny created DIRSERVER-2276:
--------------------------------------------

             Summary: Index like (&(modifyTimestamp>=20190429000000Z)(modifyTimestamp<=20190430000000Z)) should be fast
                 Key: DIRSERVER-2276
                 URL: https://issues.apache.org/jira/browse/DIRSERVER-2276
             Project: Directory ApacheDS
          Issue Type: Improvement
          Components: search
    Affects Versions: 2.0.0.AM25
            Reporter: Emmanuel Lecharny
             Fix For: 2.0.0


When we use an indexed attribute, like on {{modifyTimestamp}}, searches done with a filter like {{(&(modifyTimestamp>=20190429000000Z)(modifyTimestamp<=20190430000000Z))}} should leverage the fact that the values are ordered to limit the number of candidates.

That would require some analysis of the filter to see if we have such double boundaries.
