Writing terms/freq pairs directly to the inverted file

Hi, I would like to by-pass the IndexWriter and directly write the terms and their frequencies to the index (and may proximity info later on). I might have missed any discussion if previously. As far as I know, the high level API in Lucene only allows you to add documents (which are populated
