thanks Patrick

A question - does this technique also work if for example a job  
appears in multiple locations (melbourne & sydney), or it appears in  
multiple categories i.e. developers/software engineers/web programmers

You can do that with a single view:

In the map, emit for each field key [fieldname,fieldvalue] and value  
In the reduce, set it to '_count' (instead of a js function) to use  
the fast built-in reduce.

Then you can query that view with  
startkey=[fieldname]&endkey=[fieldname,{}]&group=true to see all the  
values in that field.

You don't really need _count, but that might be useful if you wanted  
to have some minimum of how many times a term is used before you  
include it.
