Thanks for your prompt response. What happes when more than one document has the same score? How are the results then ranked?
Equivalent scoring documents are then subsorted by document insertion order by default.
With the 1.4 version of Lucene, there is a very sophisticated way to sort, and you could choose to sort by "relevance" (rank/score), and then sub-sort by some other field value (ascending or descending) and now within even the latest unreleased version a comparator feature was added so you could develop your own mechanism for sorting given two documents.
