I believe the document level boost translates into boosts for all the fields. If so, the question is what type your fields are. The primitive fields (int, bool, and - importantly - string) do not have boosts enabled by default. Try setting omitNorms=false on field definition and see if the reindexing will help. Search for omitNorms at http://wiki.apache.org/solr/SchemaXml for more details.
