    KWIH search does not retrieve new headings immediately

    Question

    When I add new headings, why don't my headings keyword (KWIH) searches immediately retrieve them? There is a delay between the time the heading is added and the heading becoming findable via KWIH searches

    Answer

    Keyword in headings (KWIH, or headings keyword) data is not updated on the fly.

    Keyword index data are stored in keyword files on the server.

    But headings keyword indexed data is stored in DR$HEADING_CONTEXT tables in the database, which are not updated immediately, as additional processes and objects are involved in building and maintaining this indexed data. Jobs to update this data run at regular intervals, and only after the jobs run will your new headings be available via KWIH.

    As a result, you may notice a delay between the time you save a new heading to the database and the time it becomes retrievable via a KWIH search in the Voyager clients or WebVoyage.
