Subject Re: What does Sort.RELEVANCE do?
Date Thu, 06 Nov 2008 19:48:53 GMT

Section 5.1.2 of LIA also explains this.

Sort.RELEVANCE sorts by relevance score, descending, breaking ties by  
sorting by doc ID, ascending, and s the default if you don't specify a  
sort order.

Sort.INDEXORDER sorts only by doc ID, which is not the default sort.
