> The {{TermContext}} class has a reference to the top reader context of the
> IndexReader that was used to build it. So if you build a {{(Span)TermQuery}}
> that references a {{TermContext}} and this query gets cached, then it will
> keep holding a reference to the index reader, even after the latter gets
> closed.
