queryParser and sorting question

[Enrique Lamas]

Hi,
I'm, trying to execute a query to find some words, and I'm using
QueryParser queryParser = new MultiFieldQueryParser(new String[] {"tags", 
"title"}, ProcessConstants.analyzer);
Query query = queryParser.parse("word1 word2 word3");

I want to show the results sorted like this:

first, documents containing all of the three words, and this documents 
sorted by one of the index fields.
Next, documents containing two of the words, also sorted by the same field 
like before.
And so on.

¿How can I do this?

I wold like to avoid executing several queries of this kind:
"word1 + word2 + word3"
"word1 + word2 - word3"
"word1 - word2 + word3"
"word1 - word2 - word3"
.....

Thanks
