Boosting and copy fields

Hi,

How does the copy field with boosted fields? If I have three fields
with different boost values and they all get copied into a copy field,
are these boosts taken into account during searching?

Cheers
Rob

They are all multiplied together (lucene does this in the indexing
code as the index format only supports one boost per unique field per
document).
