I was really surprised to see that

Improved search performance
was supposed to be available in the first VBulletin 4 release. My search function was downgraded significantly with 4; it no longer highlights relevant sections of posts - it simply identifies entire threads where the search subject was somewhere discussed. It went from a good search function to a basically useless one.

Is there something the matter with my Forum package or is this going to be fixed or ????
