[Xapian-discuss] Document and folder suggestions

I'm working on a document manager using Xapian. If you are familiar  
with, it will hopefully be something similar to Devonthink on Mac.
There are two crucial features, finding similar documents and  
suggesting an existing folder for a document. Xapian website claims to  
do that:
"Relevance feedback - given one or more documents, Xapian can suggest  
the most relevant index terms to expand a query, suggest related  
documents, categorise documents, etc."

Currently to find related documents I get a document, create a one  
item rset, get eset of max size 100 of it and search those terms to  
get a list of documents. Here is the code:

Xapian::RSet rSelection=Xapian::RSet();
Xapian::ESet eset = enquire.get_eset(100, rSelection);
Xapian::Query query(Xapian::Query::OP_OR, eset.begin(), eset.end());
Xapian::MSet matches = enquire.get_mset(0, 10);

and here are my questions:
1) Is there a better way to get similar documents for a given document?
2) Is there way to suggest a folder for a given document to be  
classified in?

Thank you very much in advance.
