A method and system using metadata about a data collection, useful for access and searching. The metadata to comprise associations of DetailSelectors to data items describing the data Items. DetailSelector membership in groups provides context for member DetailSelectors. Boolean queries comprising such DetailSelectors and association links to GlueSelectors at one or more levels and eventually to Items, match a predetermined collection of data in the target collection. Such metadata may be used to present choices to a user for terms to add to a query while ensuring a suitable match to the query. Information about Groups of DetailSelectors and Groups of GlueSelectors, as well as information about content of a GlueSelector, may be presented to a user to provide context to the selected DetailSelectors describing the target items. |
