Is it possible to use Sphinx with Postgres?

edit

I need configure something for search's in Askbot work with Postgres FTS?

No, the configuration for that is built in. If you run migrations FTS will be set up. There is also a management command init_postgresql_full_text_search. If you are bypassing migrations with syncdb --all, then run that command afterwards. The command can be run many times without any issues.

How do I run this management command?

python manage.py command_name

./manage.py init_postgres_full_text_search This command does't run.

edited my comment - there was typo in the name. all askbot's management commands are listed in the documentation.

What typo error? I don't find this command in documentation page. When I try run above command i get this message: Unknown command: 'init_postgres_full_text_search'

I find typing ./manage.py --help (the correctly command is: init_postgresql_full_text_search)

yes, that's it.

I have problems with search yet. I have a word "problema" within a question. If I search for this word the system no returns nothing. Do you have any ideia how I can resolve this issue?
