Member Function Documentation

bool OdnQNode::foundOrderedProx (  int    currPos, int    wsize, QnList *    cl, int    ith )  [private]

recursively find matching windows for ordered proximity operator. we know how many entries are coming. total requirement is sum of the sizes of each child list + 2*dCnt

void OdnQNode::orderedProxList (  int    numDocs )  [private]

Prune proximity list for ordered proximity operator.

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

Intersect the doc lists of the children of this node. Reimplemented from ProxNode.
