On Sun,
Hi all,
How come in 4.8.1, the document.setBoost method is missing. So what is the
method for document level boost now?

inking it would be nice to store a full float in an optional
document boost file. Perhaps with variable bytesize. But that would take
a lot of effort to update all related code.
Is there an easier way out here? Perhaps variable byte size per norms

Hi Mike, I think this issue probably belongs in the Solr lists since
it looks like you're indexing through it.
I did a really quick test re-adding a Solr example document but adding
a document boost of 10...
the fieldNorm increased by a factor of 10 as expected (explain below).

Then maybe it should simply be removed from Luke's display as you
