Dick Bourke of Engineering.com recently shared a primer on current search and discovery solutions. He writes, “I’ve written several posts describing Search & Discovery Solutions (SDSs).

Search engines operate with an index – an optimized file format that supports rapid data access and display of search results. They usually do not store the complete sources. A search engine must give fast results. For example, one hi-tech manufacturing company reports that search results display in less than two seconds when accessing 16 million items and metadata from within 24 million documents, drawings and images. The usual approach to SDS indexing is based on text values. This is in stark contrast to relational databases that store data in tables, records, attributes and values.
