You have to open an IndexReader in order to walk the postings of newly indexed docs.
EG after indexing the doc, ask for a new near-real-time reader (IndexWriter.getReader()), then use the postings API (TermDocs/TermPositions in 3.0.x, but in trunk, with the flex API, DocsEnum/DocsAndPositionsEnum) via IndexReader.
