solrj, boost and schema.xml

[Marc SCHNEIDER]

Hi,

I defined fields in my schema.xml using the boost attribute.
Now I'm using Solrj to index my documents so after having created a
SolrInputDocument I use the addField method.
A boost parameter can be provided.
But how can I read the boost value I defined in schema.xml for that field so
that I can pass it to the addField method?

Thanks in advance,
Marc.
