-------------------------------------

IR/IW already try to do this
{quote}
I don't think so? I'll attach a patch with a trivial test basically
demonstrating what I was seeing.
It sometimes passes!!!!!
{noformat}
public void test() throws Exception {
TermRangeQuery query = TermRangeQuery.newStringRange("field", "a", "z",
true, true);
searcher.search(query, 5);
searcher.close();
reader.close();
searcher.search(query, 5); // are you serious?
}

> add checks/asserts if you search across a closed reader

> Reporter: Robert Muir

> if you try to search across a closed reader (and/or searcher too),
> there are no checks, not even assertions statements.
> this results in crazy scary stacktraces deep inside places like FSTs/various
> term dictionary implementations etc.
> In some situations, depending on codec, you wont even get an error (i'm sure
> its fun when you try to retrieve the stored fields!)
