當向索引添加長文本時，Neo4j - 500內部服務器錯誤

我正在使用Neo4j-community-1.9.M04，與python休息客戶端（py2neo 1.4.5）連接。當我嘗試向索引添加長文本時，服務器返回500內部服務器錯誤。當向索引添加長文本時，Neo4j - 500內部服務器錯誤

使用py2neo客戶端，我是這樣的：

everything_idx = gdb.get_or_create_index(neo4j.Node, "everything", config={"type": "fulltext"}) 
everything_idx.add("everything", long_text, recommendation_node)

哪裏long_text是從URL和recommendation_node解析含有可變文本節點比如我想要索引。

這是我在py2neo日誌：

INFO 2013-03-05 11:47:17,855 rest 11104 1108 POST /db/data/index/node/everything {'Content-Type': 'application/json', 'X-Stream': 'true', 'Accept': 'application/json', 'User-Agent': 'py2neo/1.4.6 (win32; python/2.7.2)'} (47486 bytes)

在Neo4j的日誌，我有以下幾點：的console.log：

我認爲問題可能是我使用的其他客戶端，所以我改變了它（我試過neo4jrestclient第一）。

任何想法？

你可以嘗試省略此PARAM的要求嗎？ ''X-Stream'：'true'' – ulkas 2013-03-05 10:53:23

你的長文本有多長？我認爲它試圖創建一個位置標題，這對全文索引沒有意義。請提出一個girhub問題http://github.com/neo4j/neo4j/issues – 2013-03-05 11:07:15

沒有改變 – 2013-03-05 11:18:40

原來，將此節點添加到全文索引失敗的原因是它沒有在事務中執行。我試着用下面的代碼，使用neo4jrestclient與事務和它的作品：

import urllib2, logging, logging.config, pdb, traceback 
from neo4jrestclient.client import GraphDatabase, Node, Relationship 

gdb = GraphDatabase("http://localhost:7474/db/data/") 

everything_idx = gdb.nodes.indexes.create("everything_", type="fulltext", provider="lucene") 
node = gdb.node(name="Node1") 

with gdb.transaction() as tx: 
    try: 
     request = urllib2.urlopen("http://www.tripadvisor.com/Restaurant_Review-g35805-d451303-Reviews-Ramova_Grill-Chicago_Illinois.html") 

     if request.getcode() == 200: 
      long_text = unicode(request.read(), "utf-8") 
      everything_idx["everything"][long_text] = node 
    except Exception as e: 
     pdb.set_trace()
