void hits_add (const CQueryNode &NodeFrom, vector< CHit >::const_iterator First)
add the hit list of "NodeFrom" to the back of "First"

Detailed Description

An abtsract class for binary logical operations on nodes (and, or). It contains instances of three major logical operation (union, intersection and difference) which were slightly modified to deal with CQueryNode::m_Hits and CQueryNode::m_Occurrences simultaneously.
