Introduction to Guided Search
Almost every new processing or review application that I have seen over the last year has featured a left hand navigation window that enables users to dynamically filter the collection by Author, Date, Type and more. You can call this faceted navigation, guided search or browsing navigation, but it boils down to the user’s ability to actively browse/filter the collection by metadata characteristics and categories that have been extracted from the index. Although this seems like just another way to construct a search, this feature offers a lot more to the discerning user. In older platforms, users had to run reports on their collections to extract the summary population metrics across different fields. The first one that I recall was the Tally function in Summation. This could only be done one field at a time, but unlike most static reports, you could generate the tally numbers on a set of search results instead of the entire collection. Current review, processing and even archiving products like Clearwell, Relativity, Introspect and Symantec’s Discovery Accelerator can generate these hierarchical ‘facets’ across multiple fields and display the total and item level counts dynamically in real time.
