This thread describes precisely one of the motivations behind the  
"flexible indexing" design.  It's already implemented in KinoSearch,  
using a unified postings file.  There is no "boosting term query"  
class -- TermScorer adjusts based on whether the postings format  
specifies boost per-position or per-document.
