Evaluates the individual GroupJunctions and CompositeGroupJunctions and expands the individual
results so obtained to the query from clause iterator level ( i.e top level iterators). The
expanded results so obtained are then merged (union) to get the ORed results.The evaluated
result of an AllGroupJunction will always be of the query from clause iterator level (top
level) which can be ORed or ANDd with filter evaluable subtree CompiledJunction.
