I rewrote the queries for help so it should be more useful. Previously if you did help and it returned more than 20 topics it would just show you the first one (help as would just show help masters), now it will return the number of topics found and the first 20 (meaning you should narrow down your help query a bit).

Now it will look for an exact match first. If it can't find one it will look for a word match. If it can't find one it will look for a substring. Hopefully this should make your searches easier.
