evaluate proximity operator against a document Prunes proxList to remove any entries that are no longer relevant to scoring this operator.

virtual void ProxNode::updateDocList (  int    numDocs )  [inline, virtual]

Intersect the doc lists of the children of this node. Implements QueryNode. Reimplemented in OdnQNode, UwnQNode, PassageQNode, and SynQNode.
