Cloudsearch Prefix query ignoring words after a spac

I'm trying to write a query that works similar to autocomplete. I cannot use a suggester as I also need to add a filter query. I'm using the below query but it's not ignoring words preceded by a space.

q=(and ( prefix 'lond' ) (not (prefix ' lond') ) )

E.g. This returns City of London where it should only return London

Any ideas?

The problem was with the way Amazon tokenizes Strings, splitting on space in paticular. To work around this, I have created a new index field called autocomplete_name where I simply join the String with underscores.

So City Of London becomes City_Of_London which is perfect for autocomplete.
