erreur lors de l'indexation d'un document avec pylucene

Question

Je souhaite indexer certains fichiers et y récupérer des informations.

J'utilise ce morceau de code en python document index:

import sys ; 
import lucene ; 

from java.io import File ; 
from org.apache.lucene.analysis.standard import StandardAnalyzer ; 
from org.apache.lucene.document import Document, Field ; 
from org.apache.lucene.index import IndexWriter, IndexWriterConfig ; 
from org.apache.lucene.store import SimpleFSDirectory ; 
from org.apache.lucene.util import Version ; 

if __name__ == '__main__': 
lucene.initVM(); 
indexDir = SimpleFSDirectory(File("myProjects/python/")) ; 
writerConfig = 
IndexWriterConfig(Version.LUCENE_4_10_1,StandardAnalyzer()); 
writer = IndexWriter(indexDir,writerConfig); 

print "%d docs in index" % writer.numDocs(); 
print "Reading lines from sys.stdin..." 
n = 0; 
l = 0; 
for n, l in enumerate(sys.stdin): 
    doc = Document ; 
    doc.add(Field("text", l, Field.Store.YES, Field.Index.ANALYZED)); 
    writer.addDocument(doc); 
print "Indexed %d lines from stdin (%d docs in index)" % 
(n,writer.numDocs()); 
print "Closing index of %d docs..." % writer.numDocs(); 
writer.close(); 

mais je face à cette erreur:

Traceback (most recent call last): 
File "/home/ahoora/myProjects/python/index.py", line 24, in <module> 
doc.add(Field("text", l, Field.Store.YES, Field.Index.ANALYZED)); 
TypeError: descriptor 'add' requires a 'Document' object but received 
a 'Field' 

Comment puis-je résoudre ce problème?

Merci

Il est maintenant résolu. Je devrais écrire:

doc = Document();
