Custom dictionary with Town Names

Hi,

short version:
can i have a custom dictionary with spaces in the words?

long version:
i'm trying to use aspell to check and suggest  town names.

I've built a custom dictionary with all the words from the town names.

For example:
These are the towns:
Vila da  Barquinha
Vila Nova de Gaia

it creates the following words:
vila
nova
da
barquinha
gaia
de

The user inputs "villa nova de barquinha",

currently aspell suggests: villa -> vila
But "vila nova de barquinha" doens't exist.
It should suggest a valid name  like "Vila da  Barquinha" or "Vila
Nova de Gaia".

I think that if i could create a dictionary with a groups of words
instead of single words, it could work.

Is this possible?

from the docs, http://aspell.net/man-html/Words-With-Symbols-in-Them.html
it says it's difficult, but i can't understand if it's possible.

Thanks for any help.

Regards,
Joel Alexandre
