Google discriminates Joomfish languages

[richper]

If this doesn't belong here please excuse-moi or move it. I think it has to do with different things: Sobi2, Joomfish, SEO, etc.

I have a website with 2 languages, English is default and Spanish is translated with Joomfish (This after I modified the whole site, before it was the other way around).

I recently (over a week) created a new page called "Bilingual Housing Glossary". This page started appearing in google search very quickly when looking for "Housing Glossary" and adding "Bilingual" or ".cl" in advanced search to reduce scope. But if I did (and still do) a search with the Spanish counterpart "Glosario de Vivienda" either with or without the scope reducing terms, Google finds absolutely nothing.

With my older pages Google finds pages in both languages (even bits of body text), so it gives me the idea that it's just a question of time.
I have links to both versions in my sitemap, I have sent both index pages to googlebot, but no change.
Do you know why this happens? Is there some way to get Google to retrieve the Spanish version as quickly as the default version?

Thanks.
