Boost value is multiplied with score. Or in other words it is a multiplication factor in score calculation. > Should they be relative? Yes. > Are there any standard values? No. "The default value of field boosts, logically, is 1.0. During indexing, a Document can be assigned a boost, too. A Document boost factor implicitly sets the starting field boost of all fields to the specified value. Field-specific boosts are multiplied by the starting value, giving the final value of the field boost factor."

I don't know it is the best way but using page rank as a document level boost during indexing is the easiest way, I guess. You can probably do it at query time also but I don't know how to do it in Lucene.
