    • Article Type: General
    • Product: Aleph
    • Product Version: 20

    Problem Symptoms:
    Searching data in Library of Congress catalog by z39.50 results in error:

    search failed at opac rc=1

    Defect on LOC side

    This answer was published in the Aleph Users List server:

    "I received this from the person at LC who works with the Z39.50 connection:

    Yes our keyword indexes are not working right now. I'm attempting to get the problem corrected.
    If you can configure left-anchored Z39.50 searches in your client, you can continue to search us right now. Below is a comparison.
    Title keyword
    @attr 1=4 @attr 2=3 @attr 3=3 @attr 4=2 @attr 5=100 @attr 6=1

    or just

    @attr 1=4

    (keyword is our default)

    Left-anchored/right truncated
    @attr 1=4 @attr 2=3 @attr 3=1 @attr 4=1 @attr 5=1 @attr 6=1

    The key attribute is the Completeness attribute -- set it to "first in field"

    Additional Information

    In table $alephe_tab/z39_gate/z39_gate_LOC.conf add "p=1" to the relevant index, e.g. find WTI u=4 t=l,r,b s=pw c=1 p=1 and restart Z39 Gate
