Changing Xapian stemming language

[Mario Menezes]

Hi,

  I'm new to django-haystack and xapian. I've got them to work and I would like to change the stemming language used in Xapian.

  I've set 'HAYSTACK_XAPIAN_LANGUAGE':'portuguese', in my django settings. My Haystack entry looks like:

HAYSTACK_CONNECTIONS = {
    'default': {
        'ENGINE': 'haystack.backends.xapian_backend.XapianEngine',
        'PATH': os.path.join(os.path.dirname(__file__), 'xapian_index'),
        'HAYSTACK_XAPIAN_LANGUAGE':'portuguese',
    },
}

 Is this enough? Is this the correct language spelling ou code to use? Or should be something like ISO country codes? Could'nt find anything in docs"

 Thanks,

Mario

Hi Mario,

The language passed to the backend via `HAYSTACK_XAPIAN_LANGUAGE` is directly passed to Xapian with alteration so you should be able to use any of those listed here: http://xapian.org/docs/apidoc/html/classXapian_1_1Stem.html#6c46cedf2047b159a7e4c9d4468242b1

Once you've done that, you'll need to rebuild your index to have the term stemmed in your language of choice.

Hi David,

 Thanks for your quick answer. I changed my language definition to "pt" but it seems it could be "portuguese" as I had set initially.

  Thanks again.

Sure thing.  I think either 'pt' or 'portuguese' should work.

Hi Nasmon,

  Thanks for your answer. I just forgot to do this. David have told me to do it, but I just forgot. Stemming seems to be working now.

  Best regards,

Hi Mario,

I believe, stemming is not working correctly, yet, in the new Xapian backend. Currently, it appears to be working for English only. And as stated in a previous post: Use HAYSTACK_XAPIAN_LANGUAGE directly in settings.py and not in HAYSTACK_CONNECTIONS. pt and  portuguese are both fine.
