如何使用Elasticsearch进行搜索(How to use search with Elasticsearch)

 我使用python 2.7.11和djnago 1.10.2。 我创建了产品模型并在我的数据库中保存了1000个产品。（postgrelsql）实际上，我使用了Django elasticsearch，但它不起作用。 其搜索只基于产品名称，我需要如果搜索类别，颜色等，然后​​显示相关的产品。 我试了一下例子。 
 
from haystack import indexes
from product.models import Product

class ProductIndex(indexes.SearchIndex, indexes.Indexable):
    text = indexes.CharField(document=True, use_template=True)
    product_name = indexes.CharField(model_attr='product_name')
    product_colour = indexes.CharField(model_attr='product_colour')

    def get_model(self):
        return Product

    def index_queryset(self, using=None):
        return self.get_model().objects.all() 
 
 我创建了ProductColour模型并在产品模型中使用了product_colour外键。 如果我搜索product_colour，然后显示所有相关的数据。 
 
 遵循一些步骤： -  
 
 
 
 安装django-haystack。 
 
 
 在INSTALLED_APPS settings.py文件中添加haystack。 
 
 
 修改settings.py文件。 
HAYSTACK_CONNECTIONS = {
    'default': {
        'ENGINE': 'haystack.backends.simple_backend.SimpleEngine',
    },
}
 
 
 在urls.py中添加了网址。 
urlpatterns = patterns('',
    url(r'^/search/?$', MySearchView.as_view(), name='search_view'),
)
 
 
 产品型号。 
class Product(models.Model):
    product_name = models.CharField(max_length=100)
    product_description = models.TextField(default=None, blank=True, null=True)
    product_colour = models.ManyToManyField(ProductColour, blank=True, default=None)
    .......
    .......
    .......
 
 
 search.html。 
<form method="get" action=".">
    <table>
        {{ form.as_table }}
        <tr>
            <td>&nbsp;</td>
            <td>
                <input type="submit" value="Search">
            </td>
        </tr>
    </table>
</form>
 

I using python 2.7.11 and djnago 1.10.2. I created product models and saved 1000 products in my database.(postgrelsql) Actually, I used Django elasticsearch but its not working. its search only base on product name, i required if search category, colour, etc. Then show releated product. I tryed example.
 
from haystack import indexes
from product.models import Product

class ProductIndex(indexes.SearchIndex, indexes.Indexable):
    text = indexes.CharField(document=True, use_template=True)
    product_name = indexes.CharField(model_attr='product_name')
    product_colour = indexes.CharField(model_attr='product_colour')

    def get_model(self):
        return Product

    def index_queryset(self, using=None):
        return self.get_model().objects.all() 
 
I created ProductColour models and used product_colour foreignkey in product moedls. If i search product_colour then display all releated data.
 
Following some steps :-
 
 
 
Install django-haystack.
 
 
Added haystack in INSTALLED_APPS settings.py file.
 
 
Modify settings.py file.
 
HAYSTACK_CONNECTIONS = {
    'default': {
        'ENGINE': 'haystack.backends.simple_backend.SimpleEngine',
    },
}
 
 
Added url in urls.py.
 
urlpatterns = patterns('',
    url(r'^/search/?$', MySearchView.as_view(), name='search_view'),
)
 
 
product model.
 
class Product(models.Model):
    product_name = models.CharField(max_length=100)
    product_description = models.TextField(default=None, blank=True, null=True)
    product_colour = models.ManyToManyField(ProductColour, blank=True, default=None)
    .......
    .......
    .......
 
 
search.html.
 
<form method="get" action=".">
    <table>
        {{ form.as_table }}
        <tr>
            <td>&nbsp;</td>
            <td>
                <input type="submit" value="Search">
            </td>
        </tr>
    </table>
</form>
