Multi-Search Definition

Multi-Search Definition

A
MULTI-SEARCH-DEFINITION
is used to define parameters for a cascade of searches to be executed by the DCE Search Server. Multi-Search Definitions are used exclusively by the
Batch Relate
or
Batch DupFinder
Utilities. It begins with the
MULTI-SEARCH-DEFINITION
keyword.
Field
Description
NAME=
This is a character string that identifies the Multi-Search. It is a mandatory parameter. The name must not match any
Clustering-Definition
nor
Search-Definition
names in the same Project.
COMMENT=
This is a text field that is used to describe the Multi-Search’s purpose.
SEARCH-LIST=
This is a string that contains the list of searches to perform. The searches should be separated by commas and enclosed in double quotes. All searches must be run against the same IDT. Maximum of 16 searches can be specified.
When the statistical output view field
IDS-MS-SEARCH-NUM
is used, the returned result refers to the search names in this list so that the returned value 1 means the first search in this list, value 2 means the second search in this list etc. See the
Statistical Fields
section for more information.
IDT-NAME=
This is a character string that identifies the IDT over which the Multi-Search is to be performed. It is a mandatory parameter.
SOURCE-DEDUP-MAX=
Multi-Search processing can keep track of the candidate records processed in a particular search to avoid reprocessing them when they are retrieved as candidates in a later search (in the
Search-List
). This is useful and appropriate only if all searches use the same
Score-Logic
. This parameter specifies the number of records that will be remembered. The default value of 0 disables this feature.
DEDUP-PROGRESS=
A parameter that controls the deduplication process. The
DupFinder
process treats each IDT record as a search record instead of reading search records provided by a client. Normally the search process does not return control to the client until a duplicate is found. This may take a long time if the are very few duplicates in the IDT. This parameter is used to specify the maximum number of IDT records to be processed before returning control to the client process. This gives the client the opportunity to write progress messages. The default value of 0 disables this feature.
OPTIONS=
A comma separated list of keywords used to control various search options:
  • FULL-SEARCH
    specifies that a Multi-Search is to process all searches in the list rather then returning on the first search that returns some data.
