django-haystack+solr实现搜索

1.首先下载solr。http://mirror.bjtu.edu.cn/apache/lucene/solr/3.6.1/apache-solr-3.6.1.zip下载解压即可

cd example/

java -jar start.jar

即可启动solr了，可以进入http://localhost:8983/solr/admin/看看效果。

ps. 这里有个地方要注意的，将solr/conf/stopwords.txt改名为stopwords_en.txt，不然会出错的

2.安装pysolr。sudo pip install pysolr

haystack就不介绍了，看上篇就知道了。

3.修改settings.py

HAYSTACK_CONNECTIONS = {
'default': {
    'ENGINE': 'haystack.backends.solr_backend.SolrEngine',
    'URL': 'http://127.0.0.1:8983/solr'
},

}

4.新建models如下：

class Blog(models.Model):
    title = models.CharField(max_length=30)
    content = models.CharField(max_length=140)
    created_time = models.DateTimeField(auto_now=True)

    def __unicode__(self):
        return self.title

5.在blog目录下新建search_indexes.py：

-- lang: python -->
import datetime
from haystack import indexes
from blog.models import Blog

class BlogIndex(indexes.SearchIndex, indexes.Indexable):
    text = indexes.CharField(document=True, use_template=True)
    title = indexes.CharField(model_attr='title')
    content = indexes.CharField(model_attr='content')

    def get_model(self):
        return Blog

    def index_queryset(self):
        return self.get_model().objects.all()

6.新建templates/search/indexes/blog/blog_text.txt：

{{ object.title }}
{{ object.content }}

7.在urls.py中加入(r’^$’, include(‘haystack.urls’)),

8.新建templates/search/search.html：

Search


    
        {{ form.as_table }}
        

    {% if query %}
        
Results

        {% for result in page.object_list %}
            

                Title: {{ result.object.title }}
            
            

                Content: {{ result.object.content }}
            
        {% empty %}
            
No results found.
        {% endfor %}

        {% if page.has_previous or page.has_next %}
            

                {% if page.has_previous %}{% endif %}« Previous{% if page.has_previous %}{% endif %}
                |
                {% if page.has_next %}{% endif %}Next »{% if page.has_next %}{% endif %}
            
        {% endif %}
    {% else %}
        {# Show some example queries to run, maybe query syntax, something else? #}
    {% endif %}

9.将schema.xml导入：python manage.py build_solr_schema > /path_to_solr/example/solr/conf/

10.重建索引：python manage.py rebuild_index

大致流程就这样的。
