Hi, Checkout for the following lines in the documentation of IndexReader: * "An IndexReader can be opened on a directory for which an IndexWriter is opened already, but it cannot be used to delete documents from the index then. " * "Once a document is deleted it will not appear in TermDocs or TermPostitions enumerations. Attempts to read its field with the document(int) method will result in an error. The presence of this document may still be reflected in the docFreq(org.apache.lucene.index.Term) statistic, though this will be corrected eventually as the index is further modified."
Hope this helps.

One runtime problem however remains. I cannot delete any documents. I store documents like this: IndexWriter iw = new IndexWriter( new File(Constants.INDEX_FILENAME), new StandardAnalyzer()); Document document = new Document(); ... document.add(new Field("doc", doc, Field.Store.YES, Field.Index.NO)); iw.addDocument(document); iw.optimize(); iw.close(); Which works fine. But deleting them like this: Directory fsDir = FSDirectory.getDirectory(new File( Constants.INDEX_FILENAME)); IndexReader ir = IndexReader.open(fsDir); ir.deleteDocuments(new Term("uid", uid)); ir.close(); Has absolutely no effect. I also tried delete on the IndexWriter - no effect. Please help! I don't know where to investigate any further!
