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

<!-- lang: python -->
HAYSTACK_CONNECTIONS = {
'default': {
'ENGINE': 'haystack.backends.solr_backend.SolrEngine',
'URL': 'http://127.0.0.1:8983/solr'
},

}

4.新建models如下：

<!-- lang: python -->
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：

<!-- lang: html -->
{{ object.title }}
{{ object.content }}

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

8.新建templates/search/search.html：

<!-- lang: html -->

<h2>Search</h2>

<form method="get" action=".">
<table>
{{ form.as_table }}
<tr>
<td> </td>
<td>
<input type="submit" value="Search">
</td>
</tr>
</table>

{% if query %}
<h3>Results</h3>

{% for result in page.object_list %}
<p>
Title: {{ result.object.title }}
</p>
<p>
Content: {{ result.object.content }}
</p>
{% empty %}
<p>No results found.</p>
{% endfor %}

{% if page.has_previous or page.has_next %}
<div>
{% if page.has_previous %}<a href="?q={{ query }}&page={{ page.previous_page_number }}">{% endif %}« Previous{% if page.has_previous %}</a>{% endif %}
|
{% if page.has_next %}<a href="?q={{ query }}&page={{ page.next_page_number }}">{% endif %}Next »{% if page.has_next %}</a>{% endif %}
</div>
{% endif %}
{% else %}
{# Show some example queries to run, maybe query syntax, something else? #}
{% endif %}
</form>
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。
