description System and methods for performing search and retrieval operations over multiple databases, the system and methods being suitable for use in combination with databases of different kinds managed by different database management systems, the system and methods also being suitable for use in combination with databases resident on different computers in a computer network environment. The system and methods in their simplest application search each of a pair of database segments incrementally, using the incremental results of one search to direct the processing of the other search. The methods may be nested, and the system may be used in multiple instances, to effect searches on combinations of any number of database segments.
