ok, now I remembered something from the book Lucene in Action, it
said something about "word distance". So that's why they returns
different results. But still, when I remembered when I went to
Google Adwords and get the new Maximum CPC estimates for phases
containing same words but with different orders, they always
treated them to be the same by showing the same statistics.
Why?
What does the "explain" link tell you about the differences? If I
recall correctly, Nutch generates a PhraseQuery for your terms and
OR's that in with TermQuery's, which would favor documents that have
the terms in the order listed. The explanation will tell all.

When I went to mozdex.com which is using Nutch, I realized that
the search term "good man"(no double quotes in actual search term)
returns different search result than the search term "man
good" (also no double quotes in actual search term). I went to
Google and they are doing similar thing. Why? I thought that all
terms are connected with AND by default, so they should return the
same search result.
Many thanks.
