[Xapian-devel] Explanation of how Eset works

[aarsh shah]

Hey guys hi.I am trying to understand how Xapian works .I read the
Theoretical Background to Xapian doc
and the report by Salton and Jones.I still cant seem to understand how Eset
works How exactly does Xapian add terms to expand a query ? Assuming we
have a list of the k most important terms, how do we decide which term to
add to the query and will be in context with the query ?

And to decide r in W(t)=rw(t), is r obtained from the user every time a
MSET returned and updated and stored for a term every time a query is
performed ?

Thanks for your time  :)

-Regards
