Hi I have document with fields like (title, content, datetime) I want to sort the results with the following formula
1) title boosts 2.5
2) content boost 1.5
3) IMPORTANT (boost those documents that is newer means datetime field is near today date) boost 3
how can I write a query considering the above criteria what should I do for #3
any help would be greatly appreciate.
+title:foo^2.5 +content:bar^1.5 datetime:20100721^3
Obviously, fill in appropriate values for the datetime field. The key here is that the datetime term is not a required term; it only functions increase the score for documents that match the term. You can add another datetime term for yesterday's date, and another for the day before, and so on, while decreasing the boost as you get farther away from today's date.
