LiveTrix: under the hood
•Search terms are sent to all databases in the background.
•The first 300 titles from each database are retrieved. These titles are indexed both as a string and word for word, as well as counted. A relation network is built up. From then on, the system knows in which databases these terms occur.
•In the next query, suggestions about databases (“likely sources”) are given on the basis of these ever expanding indexes.
•Dito for suggestions about word relations.
•The indexes are also used for correcting typos and word/phrase suggestions.
•Suggestions about similar sounding phrases are given upon phonetic matches (“Soundex”).
