[jira] [Created] (OAK-2873) Performance problems with many "or" conditions

Thomas Mueller created OAK-2873:
-----------------------------------

             Summary: Performance problems with many "or" conditions
                 Key: OAK-2873
                 URL: https://issues.apache.org/jira/browse/OAK-2873
             Project: Jackrabbit Oak
          Issue Type: Bug
          Components: query
            Reporter: Thomas Mueller
            Assignee: Thomas Mueller


XPath queries with many "or" condition (around 3000) of the following form can result in a performance problem:

{noformat}
contains(...) or x=1 or x=2 or x=3 ...
{noformat}

This is somewhat similar to OAK-2738, but not quite the same.
