Look for the static factory methods on IndexReader.

Thanks Mark.
I have identified the spot where I need to do the surgery. However, I
discover that IndexReader is abstract, but it seems crazy that I need
to make a concrete class for which I have no need to add any of my own
logic... Is there a suitable subclass I can use? The documented ones
- FilterIndexReader, InstantiatedIndexReader, MultiReader,
ParallelReader - all seem too complicated for what I need. My only
requirement is to open it read-only!
Am I missing something?

So does that mean if you don't explicitly open an IndexReader, the
IndexSearcher will do it for you? Or what?
Right. The IndexReader takes a Directory, and the IndexSearcher takes
an IndexReader - there are sugar constructors though - An
IndexSearcher will also accept a String file path, which will be used
to create a Directory which is used to create an IndexReader. It will
also take a Directory, which will be used to create an IndexReader.
It will also just accept the IndexReader.
So you have to find how that IndexReader is being created (or where)
and change the code so that you get to create it, and when you do, do
it read-only. It should be easier than that roundabout info sounds.
