Thanks. Just so you know going forward, please be patient in expecting answers, especially for complex questions like this that involve fairly expert usages of Lucene. From what I can tell, you have sent the same question 3 times in a matter of less than a day. Sending more than once in a 2-3 day period is just going to make it less likely that you will get help, not more likely.
