> 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.
