Package er.neo4jadaptor.query Description

Classes for handling search queries by using the concept of layers of filters - Filter may filter out some record if it doesn't match search criteria, but may not. Results are passed to another filter which might be more strict than the previous one and so on until we get Results exaclty matching search criteria. Layers are collected in LayeringFilter class.

One filter that returns exact results is EvaluatingFilter, but it's the slowest possible one so it should be used as the last resort, probably after initial filtering using faster methods.

For almost all cases nodes/relationships are evaluated lazily as the client code requests the next record.
