Do you have access to the original documents, outside Lucene?
If so, you can avoid storing anything.
When you want to highlight, you read the document again, build a
new index (in RAM, with stored=true), do the search again (in an index
with only one document), extract highlights, destroy the index.

I've done that in the past; it works beautifully.
And the performance is not bad at all.
Well, I actually do this for each _field_ in a document I want to highlight
(for reasons I will not go to explain).

Best regards.
