------------------------------
Fix Version/s: 0.20
> Query: support "union" and "union all"
> --------------------------------------
>
> Key: OAK-904
> URL: https://issues.apache.org/jira/browse/OAK-904
> Project: Jackrabbit Oak
> Issue Type: New Feature
> Components: query
> Reporter: Thomas Mueller
> Priority: Minor
> Fix For: 0.20
>
>
> The query engine currently doesn't use an index for conditions of the type
> "x=1 or y=1". As a first step to implement this feature, we should support
> "union". The next step is to automatically convert queries with this
> condition to a union; but even if this is not implemented, the user could
> convert the query himself (manually) to a union.
> And for JSR-333, we anyway want to support union.
