foo AND (field:*^2.0 OR (-field:*)^0.5)
So, if a doc has anything in the field, it gets boosted, and if the doc does
not have anything in the field, de-boost it. Choose the boost factors to
suit your desired boosting effect.

Subject: Re: Boosting on field empty or not
OK maybe i need to describe this a little more.
Basically I want documents that have a given field populated to have a
higher score than the documents that dont. So if you search for foo I want
documents that contain foo, but i want the documents that have field a
populated to have a higher score...
Is there a way to do this?

Subject: Boosting on field empty or not
Is there a way to boost a document based on whether the field is empty or
not. I am looking to boost documents that have a specific field
populated.
