Question

Django 1.8
elasticsearch-2.3.1

settings.py

HAYSTACK_CONNECTIONS = {
'default': {
    'ENGINE': 'haystack.backends.elasticsearch_backend.ElasticsearchSearchEngine',
    'URL': 'http://127.0.0.1:9200/',
    'INDEX_NAME': 'haystack',
},
}

search_indexes.html

class VehicleIndex(indexes.SearchIndex, indexes.Indexable):
text = indexes.EdgeNgramField(document=True, use_template=True)
garage = indexes.EdgeNgramField(model_attr='garage')
plate_number = indexes.EdgeNgramField(model_attr='plate_number')
chassis_number = indexes.CharField(model_attr='chassis_number')
brand = indexes.EdgeNgramField(model_attr='brand')
model = indexes.CharField(model_attr='model')

def get_model(self):
    return Vehicle

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

示例：

实例模型品牌＆＃34; Iveco＆＃34;
使用依维柯＆＃39;我获得了正确的结果
使用＆＃34; Iv＆＃34;或者＆＃34; ec＆＃34;没有结果。

＆GT;＆GT;＆GT;＆GT;＆GT;＆GT;有什么不对？为什么忽略部分单词搜索？

其他信息

我发现了这个，但没有用：link

我认为elasticsearch_backend.py中的haystack中存在一个错误没有正确使用pyelasticsearch第868行看起来像：

self.conn.put_mapping('modelresult', current_mapping, index=self.index_name)

如果您将其替换为：

self.conn.put_mapping(doc_type='modelresult', mapping=current_mapping, index=self.index_name)

这是pyelasticsearch的预期，然后你会看到 edgengram_analyzer将添加到EdgeNgramField字段中。至少它适合我。

在elasticsearch日志中找到了这个
