3.6 - querying a no-norms field and getting document boost

[mark harwood <ma...@yahoo.co.uk>]

I have a 3.6 index with many no-norms fields and a single text field with norms (a fairly common configuration). There is a document boost I have set at index-time that will have been encoded into the text field's norms.

If I query solely on a non-text field then the ranking does not apply the document-level boost.

Without re-indexing and adding norms where I don't want them, how do I most elegantly query field "A" and factor in the doc-boost already recorded in the "text" field's norms?
I appreciate DocValues in 4.x helps in this regard but looking for a clean/fast 3.6-based solution.

Any suggestions?

Answering my own question - add optional new MatchAllDocsQuery("text") clause to factor in the encoded norms from the "text" field.
