    Z39.50 left-anchored search against Voyager database produces incorrect results

    • Product: Voyager
    • Product Version: 7
    • Relevant for Installation Type: Multi-Tenant Direct, Dedicated-Direct, Local, TotalCare



    I am trying to run a Z39.50 query against a Voyager database using the Yaz Client.  I am searching the left-anchored TALL index (Use Attribute 4) using this query:

    > f @attr 1=4 chicago

    But my results include records that do not belong with my search.  What am I doing wrong?


    For left-anchored searches, the Position Attribute must be defined. Otherwise the search is performed as a keyword search against the entire record. 

    Modify your query to this:

    > f @attr 1=4 @attr 3=1 chicago

    to find all records with the string "chicago" in the specified index starting with the first character position

    Additional Information

    See for more information on the z39.50 search attributes shown above
