Yun,
Literally you can call another QParser from the middle of a query and apply
local params to it via nested queries feature
http://searchhub.org/2009/03/31/nested-queries-in-solr/ syntax is little
bit tricky though.
But calling other QParser and attempting specify number of rows for it
makes absolutely no sense in Lucene universe. I guess you try to get
something like RDBMS or implement kind of imperative algorithm on top of
Solr. It doesn't seem possible to me. Everything here is around Boolean
Retrieval and Vector Space Model.
