Additional Query Operators

In this section we present several query language operators that are useful when querying the information within labels. First, a label restructuring operation, called Slice, is given that carves a portion from each label on a path. Next, the previously defined ClPt operation is trivially generalized to operate on the result of a Match. Finally, a Coalesce operation is defined to extract the value of a property that is distributed in several labels.
