[Xapian-discuss] Effects of passing a RSet to Enquire::get_mset()

[Rusty Conover]

Hi All,

 From my brief testing it appears that passing an RSet filled with  
documents to Enquire::get_mset() does not make much of a difference  
to the returned results.

I have a search returning about 1000 results, when I add an RSet  
containing about 75 documents that appeared towards the end of the   
result list (about position 600 on average with a relevancy of  >  
80), there was no change.  Is this to be expected? The understanding  
I got from the documentation is that by adding documents to the RSet  
their terms would be considered more relevant, and query results  
would change.

Did I misunderstand the purpose of the relevancy set with regard to  
query evaluation?  Or may there be a bug lurking somewhere or does  
the passed relevancy set need to be bigger to have an effect?

Cheers,

Rusty
