Use administrative commands to set the default dictionary
used for Search query strings.
Before you begin
When using administrative commands, you
must use the IBM® WebSphere® Application Server wsadmin client.
See Starting the wsadmin
client for details.
About this task
You use the setDefaultDictionary command
to set the default dictionary used for Search queries. At indexing
time, when content is analyzed, an attempt is made to guess which
of the enabled IBM LanguageWare® dictionaries should be
used when applying the text analysis process. If the attempt is unsuccessful
or if the language guessed does not have a corresponding dictionary
enabled, the default dictionary is used.The default dictionary
is also used at search time. Language guessing is not used at search
time to determine which dictionary is used for text analysis, the
language is specified as part of the HTTP request. If there is a problem
loading the dictionary corresponding to the language specified or
if there is no corresponding dictionary enabled, then the default
dictionary is used.
Procedure
To specify a default dictionary for use with Search,
complete the following steps.
- Start the wsadmin client from the following
directory of the system on which you installed the Deployment Manager:
app_server_root\profiles\dm_profile_root\bin
where
app_server_root is
the WebSphere Application
Server installation directory and
dm_profile_root is
the Deployment Manager profile directory, typically dmgr01.
You
must start the client from this directory or subsequent commands that
you enter do not execute correctly.
- After the wsadmin command environment
has initialized, enter the following command to initialize the Search
environment and start the Search script interpreter:
execfile("searchAdmin.py")
If prompted to specify a service to connect to, type 1 to pick
the first node in the list. Most commands can run on any node. If
the command writes or reads information to or from a file using a
local file path, you must pick the node where the file is stored.
When
the command is run successfully, the following message displays:
Search Administration initialized
-
Check out the Search cell-level configuration file, search-config.xml,
with the following command:
SearchCellConfig.checkOutConfig("working_dir",
"cellName")
Where:
- working_dir is the temporary directory to which you want to check out the
cell level configuration file. This directory must exist on the server where you are running the
wsadmin client. Use forward slashes to separate directories in the file path,
even if you are using the Microsoft
Windows operating
system.
Note: AIX, and Linux only: The
directory must grant write permissions or the command does not run successfully.
- cellName is the name of the cell that the Search node belongs to. The command
is case-sensitive. If you do not know the cell name, you can determine it by typing the following
command in the wsadmin command processor:
print
AdminControl.getCell()
For
example:
SearchCellConfig.checkOutConfig("c:/search_temp", "SearchServerNode01Cell")
- To set the default dictionary, use the following command:
- SearchCellConfig.setDefaultDictionary(String languageCode)
Configures the default LanguageWare dictionary
used by the Search application. The default dictionary must be one
of the enabled dictionaries.
This command takes a single argument:
- languageCode is the language code for the dictionary that you
want to set as the default.
This language code typically comprises
two letters conforming to the ISO standard 639-1:2002 that identifies
the primary language of the dictionary. However, there are some codes
that additionally define a country or variant, in which case these
constituent parts are separated by an underscore. For example, Portuguese
has two variants, one for Portugal (pt_PT) and one for Brazil (pt_BR).
When using a code that also specifies a country, ensure that you use
an underscore to separate the language code and the country code rather
than a hyphen; otherwise an error will be generated.
Note: A matching
dictionary must exist in the list of configured dictionaries for the
language that you specify as a parameter.
For example:
SearchCellConfig.setDefaultDictionary("fr")
- Check in the updated search-config.xml configuration
file using the following wsadmin client command:
SearchCellConfig.checkInConfig()
- To exit the wsadmin client, type exit at
the prompt.
-
Stop the server or servers hosting the Search application, and then restart the Search servers.
The next time the scheduled task runs, persisted seedlists are retained after indexing
finishes.
