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.

I can specify Sort.RELEVANCE to Searcher.search as in:

What is the real effect of specifying the Sort argument like this?
Does Sort.RELEVANCE sorts the hits in order of the score
shown in Sect. 3.3 "Understanding Lucene scoring"
of Lucene In Action? If I use the search method without
a sort argument, is it equivalent of specifying
Sort.INDEXORDER?
