----------------------------------
Summary: Query engine: automatic expansion of "x=1 or x=2" to "(x
is not null) and (x=1 or x=2)"
Key: OAK-824
URL: https://issues.apache.org/jira/browse/OAK-824
Project: Jackrabbit Oak
Issue Type: Bug
Components: core, query
Reporter: Thomas Mueller
Assignee: Thomas Mueller
Queries with conditions of the type "x=1 or x=2" currently don't use an index.
An index (on property existance) could be used if the condition is
automatically expanded to "(x is not null) and (x=1 or x=2)". This should be
relatively easy to implement in the query engine (I hope).
