Subject Re: Sort by the number of matching fields
Date Thu, 21 Jan 2010 17:31:19 GMT
I'm not sure I understand what you are asking, but if you search for
id:5 id:6 then I think doc2 will be ranked higher, because it contains
both fields.

Or are you saying you want to rank based on the number of id fields in
the document i.e. doc2 better than doc1 because 3 better than 5?  If
that is the case you could add a new field to each document holding
the number of id fields in that document and sort on that.

Or maybe you just need to boost searches for preferred id values.
id:5^4 or Query.setBoost().
