A few problems I am noticing, please someone verify with their setup:
When viewing a thread contained in search results the search terms are only hilighted on the first page of the thread.
When searching for a PHRASE and viewing a thread contained in those results, the search terms are not hilighted at all in the results and when you click to visit page 2 in the thread it reloads the first page and the &hilight part of the URL is empty.
I don't recall these things happening with the original search schema.
