If you've generated your Query through the use of QueryParser then you really must call the Query.Rewrite before you pass the query to the scorer which goes on to the highlighter. When I said the first example what I meant was the first example in section 8.7 "Highlighting query terms". It looks like a very simple example but for me it was not a realistic example. When I see these things I want to cut and paste and use as a starting point but in this case it didn't do what I expected and I ended up confused..
