我尝试使用django-haystack(2.6.0)和solr(4.10.4)来实现两个字段搜索。我想通过ship
名称搜索我的模型或发送country
(返回给定国家/地区的船只列表)但是如果我使用document=True
定义一个字段,我会遇到问题没有结果。
我拒绝了documentation和answer,看起来相当容易。
我创建了以下search_indexes.py
:
class ShipListIndex(indexes.SearchIndex, indexes.Indexable):
text = indexes.CharField(document=True, use_template=True)
def get_model(self):
return ShipList
def index_queryset(self, using=None):
return self.get_model().objects.all()
我在我的应用程序中创建了一个新模板,指定了搜索中使用的所有字段:
search/indexes/myapp/shiplist_text.txt
{{ objects.ship }}
{{ objects.country }}
所以这是我的模特:
class ShipList(models.Model):
ship = models.CharField(max_length=200)
country = models.CharField(max_length=200)
region = models.CharField(max_length=250, blank=True)
city = models.CharField(max_length=250, blank=True)
ship_class = models.CharField(max_length=200, blank=True)
ship_type = models.CharField(max_length=200, blank=True)
remarks = models.CharField(max_length=200, blank=True)
url = models.URLField(max_length=200)
slug = models.SlugField()
和视图:
def ship_search(request):
results = None
cd = None
form = SearchForm()
if 'query' in request.GET:
form = SearchForm(request.GET)
if form.is_valid():
cd = form.cleaned_data
results = SearchQuerySet().models(ShipList).filter(content=cd['query']).load_all()
return render(request,
'core/draft/search.html',
{'form': form,
'results': results,
'cd': cd})
简单模板
{% block search %}
{% if "query" in request.GET %}
{% for result in results %}
{% with ship=result.object %}
<p>{{ ship.ship }}</p>
<p><a href="{{ ship.get_absolute_url }}">{{ ship.ship }}</a></p>
{% endwith %}
{% empty %}
<p>There are no results for your query.</p>
{% endfor %}
{% else %}
<h1>Search for posts</h1>
<form action="." method="get">
{{ form.as_p }}
<input type="submit" value="Search">
</form>
{% endif %}
{% endblock %}
然后我检查了solr接口http://127.0.0.1:8983/solr/#/myapp/query
以获取JSON响应:
{
"responseHeader": {
"status": 0,
"QTime": 2
},
"response": {
"numFound": 11,
"start": 0,
"docs": [
{
"django_ct": "core.shiplist",
"id": "core.shiplist.1",
"django_id": "1",
"text": "\n\n"
},
{
"django_ct": "core.shiplist",
"id": "core.shiplist.2",
"django_id": "2",
"text": "\n\n"
},
{
"django_ct": "core.shiplist",
"id": "core.shiplist.3",
"django_id": "3",
"text": "\n\n"
]
}
}
所以这是搜索索引中为每艘船存储的数据
我发现文本字段包含"\n\n
我猜这里的问题可能应该是这样的:
"text": "USS Arizona\nUnited States"
到目前为止,我尝试创建没有use_template
的search_indexs.py:
class ShipListIndex(indexes.SearchIndex, indexes.Indexable):
text = indexes.CharField(document=True, model_attr='ship')
def get_model(self):
return ShipList
它工作正常,我可以按船名搜索,查询输出是正确的。
{
"id": "core.shiplist.5",
"django_ct": "core.shiplist",
"django_id": "5",
"text": "USS Arizona"
},
最后我的solrconfig.xml
<?xml version="1.0" encoding="utf-8" ?>
<config>
<luceneMatchVersion>LUCENE_36</luceneMatchVersion>
<requestHandler name="/select" class="solr.StandardRequestHandler"
default="true" />
<requestHandler name="/update" class="solr.UpdateRequestHandler" />
<requestHandler name="/admin" class="solr.admin.AdminHandlers" />
<requestHandler name="/admin/ping" class="solr.PingRequestHandler">
<lst name="invariants">
<str name="qt">search</str>
<str name="q">*:*</str>
</lst>
</requestHandler>
</config>
显然我错过了一些东西,或者我不明白它是如何工作的?
答案 0 :(得分:0)
在模板中,应该如何形成搜索字段:
search/indexes/myapp/shiplist_text.txt
{{ objects.ship }}
{{ objects.country }}
..你引用的是objects
(最后是s)。正确的名称为object
,没有额外的s
:
{{ object.ship }}
{{ object.country }}
您看到的额外内容是文件末尾的换行符。保存它没有它,你将避免在你的价值的最后有一个额外的\ n。但是,它对于可搜索性并不重要。
