it.unimi.dsi.mg4j.search.DocumentIterator.dispose()
Disposes this document iterator, releasing all resources.
This method should propagate down to the underlying index iterators, where it should release resources such as open files and network connections. If you're doing your own resource tracking and pooling, then you do not need to call this method.
