奇怪的錯誤添加到飛快索引

任何人都可以幫我解決這個奇怪的錯誤，當向一個whoosh索引添加一個新文檔時，奇怪的錯誤添加到飛快索引

下面的代碼：

def add_to_index(self, doc): 
    ix = index.open_dir(self.index_dir) 
    writer = AsyncWriter(ix) # use async writer to prevent write lock errors 
    writer.add_document(**self.get_doc_args(doc)) 
    writer.commit() 

def get_doc_args(self, doc): 
    return { 
     'id':  u""+str(doc['id']), 
     'org':  doc['org__id'], 
     'created': doc['created_date'], 
     'date':  doc['received_date'], 
     'from_addr': doc['from_addr'], 
     'subject': doc['subject'], 
     'body':  doc['messagebody__cleaned_message'] 
    }

我得到以下錯誤：

TypeError('ord() expected a character, but string of length 0 found',)

    super(TermIndexReader, self).__init__(dbfile) 
    File "/usr/local/lib/python2.6/dist-packages/whoosh/filedb/filetables.py", line 502, in __init__ 
    OrderedHashReader.__init__(self, dbfile)

    File "/usr/local/lib/python2.6/dist-packages/whoosh/filedb/structfile.py", line 219, in read_byte 
    return ord(self.file.read(1))

奇怪的是，使用標準的作家（即不AsyncWriter）完全相同的代碼工作得很好。我在這裏錯過了什麼？請注意，在生產中我必須使用AsyncWriter以避免LockErrors。

我應該補充一點，我已經驗證所有輸入都是unicode字符串。 – kuhnza

作爲評論是好的，但不是你指定的錯誤的解決方案。 – n3storm

此錯誤是由某種索引損壞引起的。在我的情況下，機器在索引重建期間因另一個原因而崩潰。

您可以通過完全刪除whoosh_index文件夾內容和重建索引輕鬆解決它。

刪除whoosh索引並重建它也爲我修復了它。 – Mahn
