干草堆多场搜索(haystack multiple field search)

 嗨我使用干草堆与woosh作为搜索引擎： 
 
 我的模型如下所示 
 
class Person(models.Model):
    personid = models.IntegerField(primary_key = True, db_column = 'PID')  
    firstname = models.CharField(max_length = 50, db_column = 'FIRSTNAME')  
    lastname = models.CharField(max_length = 50, db_column = 'LASTNAME') 
    class Meta:
        db_table = '"TEST"."PERSON"'
        managed = False


class TDoc(models.Model):
    tdocid = models.IntegerField(primary_key = True, db_column = 'TDOCID')  
    person = models.ForeignKey(Person, db_column = 'PID')
    content = models.TextField(db_column = 'CONTENT', blank = True) 
    filepath = models.TextField(db_column = 'FILEPATH', blank = True) 
    class Meta:
        db_table = '"TEST"."TDOC"'
        managed = False
 
 search_index.py如下： 
 
class TDocIndex(SearchIndex):

    content = CharField(model_attr = 'content', document = True)
    filepaht = CharField(model_attr = 'filepath')
    person = CharField(model_attr = 'person')

    def get_queryset(self):
        return TDoc.objects.all()

    def prepare_person(self, obj):
        # Store a list of id's for filtering
        return obj.person.lastname

site.register(TDoc, TDocIndex)
 
 我的问题是我想做多个字段搜索 
 
 
 
 内容：xxx和人：SMITH 
 
 
 在干草堆上，它立即搜索所有这些我无法进行特定的野外搜索。 我怀疑我的索引已损坏但是： 
 
ix = open_dir("/testindex")

searcher = ix.searcher()

mparser = MultifieldParser(["content", "filepath", "person"], schema = ix.schema)
myquery = mparser.parse(content:xxx AND person:SMITH')
results = searcher.search(myquery)
for result in results:
    print result
 
 但它的工作原理和返回的正确值。 我在教程中使用标准的haystack SearchView，search.html 
 
(r'^search/', include('haystack.urls')),

Hi i m using haystack with a woosh as search engine:
 
my model looks as follows
 
class Person(models.Model):
    personid = models.IntegerField(primary_key = True, db_column = 'PID')  
    firstname = models.CharField(max_length = 50, db_column = 'FIRSTNAME')  
    lastname = models.CharField(max_length = 50, db_column = 'LASTNAME') 
    class Meta:
        db_table = '"TEST"."PERSON"'
        managed = False


class TDoc(models.Model):
    tdocid = models.IntegerField(primary_key = True, db_column = 'TDOCID')  
    person = models.ForeignKey(Person, db_column = 'PID')
    content = models.TextField(db_column = 'CONTENT', blank = True) 
    filepath = models.TextField(db_column = 'FILEPATH', blank = True) 
    class Meta:
        db_table = '"TEST"."TDOC"'
        managed = False
 
The search_index.py is as follows:
 
class TDocIndex(SearchIndex):

    content = CharField(model_attr = 'content', document = True)
    filepaht = CharField(model_attr = 'filepath')
    person = CharField(model_attr = 'person')

    def get_queryset(self):
        return TDoc.objects.all()

    def prepare_person(self, obj):
        # Store a list of id's for filtering
        return obj.person.lastname

site.register(TDoc, TDocIndex)
 
My problem is i would like to do multiple filed searches like
 
 
 
content:xxx AND person:SMITH
 
 
On haystack it search all of them at once i can't do specific field search. I suspected that my index is corrupt but:
 
ix = open_dir("/testindex")

searcher = ix.searcher()

mparser = MultifieldParser(["content", "filepath", "person"], schema = ix.schema)
myquery = mparser.parse(content:xxx AND person:SMITH')
results = searcher.search(myquery)
for result in results:
    print result
 
but it works and return's the correct value. I m using the standard haystack SearchView,search.html from the tutorial
 
(r'^search/', include('haystack.urls')),
