I've looked through Kinosearch, Serach-Indexer etc ... but could not find an "escape route".

KinoSearch or Lucene sounds like exactly what you need.

What exactly do you mean by an "escape route"? Have you tried anything since your previous request?

You'll likely get a better response if you post the code you've tried so far. Please remember to follow the writeup formating tips (use <code> and <readmore> tags).
