Hi Eric, Tnx, I just saw the example in Lucene in Action. But I am not sure how I can apply it in my case as it was used to sort the results, but what I need is to get only the records that are within a limit radius. And I want the results to be sorted according to score (text match on title ).
Tnx for pointing me to that direction, I will study it and see how I can use it. Johnny ----- Original Message ---- From: Erick Erickson <[EMAIL PROTECTED]> To: java-user@lucene.apache.org; Johnny R.

There's also an example of something very similar in Lucene In Action. Erick On 10/20/07, Johnny R.
