    • 11. LiveTrix: under the hood <ul><li>Search terms are sent to all databases in the background. </li></ul><ul><li>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. </li></ul><ul><li>In the next query, suggestions about databases (“likely sources”) are given on the basis of these ever expanding indexes. </li></ul><ul><li>Dito for suggestions about word relations. </li></ul><ul><li>The indexes are also used for correcting typos and word/phrase suggestions. </li></ul><ul><li>Suggestions about similar sounding phrases are given upon phonetic matches (“Soundex”). </li></ul>Source: Redesigning our Combine Harvester (MetaLib) (Ane W. van der Leij, University of Groningen, NL)
