Using the didump utility



Using the didump utility, you can view key components of the word index per partition. The word list is a list of all words indexed by the Verity engine; the zone list is a list of all zones; and the zone attribute list is a list of the zone attributes found by the Verity engine.

The didump executable, which starts the didump application, is located in the platform/bin directory. For more information on the specific location of this directory, see Location of Verity utilities.

For example: 

c:\coldfusion9\verity\k2\_nti40\bin\didump /common = c:\coldfusion9\verity\k2\common    -pattern llama 
c:\new\parts\00000001.did

    Viewing the word list with the didump utility

    You can view the contents of the word list for a partition by using the didump utility with the ‑words flag. The command-line syntax must include the ‑words flag and a path to a partition file, like the following:

    didump -words /z/collbldg/html/parts/00000003.did 
An alphabetical listing of the words in the word index displays, as follows:

    The columns in the display indicate the following:

    Size
    The number of bytes used by the Verity engine to store information about the word

    Doc
    The number of unique documents in which the word appears

    Word
    The total number of occurrences of a word for the partition

    To view the occurrences of a specific word or pattern, enter a command using the -pattern option, as in the following example:

    didump -pattern acronym 00000003.did

    In this example, the didump utility displays information about the number of occurrences of the word acronym. You can display the individual occurrences of a word using the -verbose option.

    Viewing the zone list with the didump utility

    The zone list contains a list of the zones identified by the zone filter. You can search the zones listed using the Verity IN operator in a query. To view the contents of the zone list, use the didump utility with the -zones flag plus the path to a partition, like the following:

    didump -zones /z/collbldg/html/parts/00000003.did

    This partition is for a collection containing the Verity Collection Building Guide in HTML. The Verity universal filter started the HTML filter by default, and indexed the documents using these zones.

    The columns in the display indicate the following:

    Region
    The total number of instances of a zone for the partition

    Viewing the zone attribute list with the didump utility

    The zone attribute list contains a list of the HTML attributes for the zones identified by the HTML zone filter. You can search the zone attributes listed using the Verity IN operator together with the WHEN operator in a query. To view the contents of the zone attributes list, use the didump utility with the -attributes flag plus the path to a partition, like the following:

    didump -attributes /z/collbldg/html/parts/00000003.did

    This partition is for a collection containing the Verity Collection Building Guide in HTML.
