"value boosts"? (boosting a multiValued field's data)
Hi. Is the "expansion" method described in the following year old post still
the best available way to do this?
http://www.nabble.com/newbie-Q-regarding-schema-configuration-tf1814271.html#a4956602
The way I understand it, indexing these
<field name="foo" boost="1.0">First val</field>
<field name="foo" boost="0.8">Less important value</field>
would just make the boost "0.8" field-wide?
Best regards,
D.

Yes... all boost values for multivalued fields are multiplied
together. Nothing we can do about that... only one norm (boost *
lengthNorm) is stored per document per unique field.
