Did you try integer arrays with GIN (inverted index) ?
I now tried this, and GIN turned out to be linear time, compared with GIST
which was acceptable time. However I tested this only for Z=infinity, for
Z=1000, GIST/GIN are both not acceptable.
Sorry, I didn't follow your problem, but GIN should be certainly
logarithmic on the number of unique words. Also, it'd be much clear
if you show us your queries and explain analyze.
