    • Using non-specific terms, phrases that are too broad
    • Lack of understanding of Boolean logic or database peculiarities
  • LiveTrix = X-Server +Metalib
    • xml
    • Working outside the box
    • Modulair, you can add/connect stuff, flexible
    • Harvesting & analysing records
    • Statistics modules (from logfiles)
      • Metalib statistics
      • SFX-statistics

      • Fulltext availability on First Selection Screen
  • 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”).
