Just a suggestion...we've experimented with indexing the values which people put into their profiles to create community navigation. The theory is that you can find people who ride in the same place, or belong to the same club. You see that navigation on the left, if you search or view members.
because we didn't want to constrain what people put in, the values are a bit over the place at the moment.
If you do see somewhere on the list you go to, or belong to a club listed and want to be included with that item, put the value in exactly as it is listed - case sensitive - to be included in that search term.
