Python django haystack没有索引

我正在使用Ubuntu13和Django1.4.5，我已经安装了solr、tomcat6（sudo-apt-get-install-solr-tomcat）djangohaystack等，它们看起来工作得很好。但是我不能做索引

search_index.py

from haystack import indexes, site
from firms_api.models import Company

class CompanyNameIndex(indexes.SearchIndex, indexes.Indexable):
    text = indexes.CharField(document=True, use_template=True)
    company_name = indexes.CharField(model_attr='company_name')

    def get_model(self):
        return Company

        def __unicode__(self):
            return self.Company.company_name

    def index_queryset(self, using=None):
        return self.get_model().objects.all()

site.register(Company, CompanyNameIndex) 

设置文件：

HAYSTACK_SITECONF = 'api'
HAYSTACK_SEARCH_ENGINE = 'solr'
HAYSTACK_WHOOSH_PATH = os.path.join(PROJECT_ROOT, 'djangobb_index')
HAYSTACK_SOLR_URL = "http://solrserver.com/solr"

比我做的还要多：

python manage.py build_solr_schema -f schema.xml
sudo mv schema.xml /etc/solr/conf/schema.xml 
sudo /etc/init.d/tomcat6 restart
 * Stopping Tomcat servlet engine tomcat6                                                                                                [ OK ] 
 * Starting Tomcat servlet engine tomcat6                                                                                                [ OK ] 

python manage.py rebuild_index

python manage.py haystack_info

Main site registered 0 index(es).

当我尝试在solr上搜索时，出现以下错误：

HTTP Status 400 - no field name specified in query and no defaultSearchField defined in schema.xml

type Status report

message no field name specified in query and no defaultSearchField defined in schema.xml

description The request sent by the client was syntactically incorrect (no field name specified in query and no defaultSearchField defined in schema.xml).

有人知道我在哪里犯错吗

谢谢

我已经安装了haystack 2.0.0测试版，现在可以使用了
