Thanks Robert for looking into it.

I think there is some confusion here. I didn't test "search body",
not sure if this was supported by cyrus 2.4 and if yes if it made
use of the index.
What I did test was "search text" and "search header".
Both used the index in 2.4 and didn't use it in 3.0
in my initial configuration.

I was able to make cyrus use the squat index file again
for header search by enabling conversation db, though I had to
disable conversation db again on our production servers because
of other problems.

I can test again if search_fuzzy_always has an influence on
the usage of the usage of the "search text".
